I want to Collect the usernames added in the PeoplePicker and display them in the textbox on the click of "Add" button for a custom aspx page.
I tried many codes but its not working.
Here is my code:
protected void btnpicker_Click(object sender, EventArgs e)
{
for (int i = 0; i < userPicker.ResolvedEntities.Count; i++)
{
PickerEntity picker = (PickerEntity)userPicker.ResolvedEntities[i];
Hashtable hstEntityData = picker.EntityData;
string accountName = Convert.ToString(hstEntityData["AccountName"]);
txtPicker.Text = "Count" + hstEntityData.Count.ToString();
txtPicker.TextMode = TextBoxMode.MultiLine;
}
}
Help Highly Appreciated.
Try the following code.
protected void btnpicker_Click(object sender, EventArgs e)
{
for (int i = 0; i < userPicker.ResolvedEntities.Count; i++)
{
PickerEntity picker = (PickerEntity)userPicker.ResolvedEntities[i];
yourTextBox.Text = "Count: " + new SPFieldUserValue(yourSPWebObject, Convert.ToInt32(picker.EntityData["SPUserID"]), picker.Key).User.Name;
}
}
This code will give all name of the users in your textbox.

On the Page, I add UserControl into GridView dynamically. So, each UserControl can contain different kind of controls ( TextBox, CheckBox, Radio Button)
say , the name of UserControl is : UserForm.
problem :
How to get a collection of control using VisualTreeHelper and check if textBox is empty.
I found a code similiar to this problem and modified it but not working.
I dont know what this means and if this is required?
list.AddRange(AllTextBoxes(child))
Should I use MyList.Select() or MyList.Where() ?
void FindTextBoxes()
{
List <TextBox> MyList = AllTextBoxes(UserForm);
var count = MyList.Where(x= > if(string.IsEmptyOrNull(x.Text));
}
List <TextBox> AllTextBoxes(DependencyObject parent)
{
var list = new List <TextBox>();
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(parent); i++)
{
var child = VisualTreeHelper.GetChild(parent, i);
if (child is TextBox)
list.Add(child as TextBox);
list.AddRange(AllTextBoxes(child));
}
return list;
}
Here's what I use.
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
var textBoxes = AllChildren(MyGridView).Where(x => x is TextBox);
}
public IEnumerable<Control> AllChildren(DependencyObject parent)
{
for (int index = 0; index < VisualTreeHelper.GetChildrenCount(parent); index++)
{
var child = VisualTreeHelper.GetChild(parent, index);
if (child is Control)
yield return child as Control;
foreach (var item in AllChildren(child))
yield return item;
}
}
Best of luck!
I want to show only few rows in DataGridview (like 1 to 10) and remaining are shown on button click..
so How can I Perform this operation..
If you have all data loaded (that means you are not doing paging on DB side for example) then keep track of page;
private int page = 0;
protected void ShowNextResults_Click(object sender, EventArgs e)
{
page++;
dataGridView1.CurrentCell = null; //required to control row visibility as we cannot hide current cell
int from = page * 10;
int to = from + 10;
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
if (i >= from || i < to)
{
dataGridView1.Rows[i].Visible = true;
}
else
{
dataGridView1.Rows[i].Visible = false;
}
}
}
This traverse results forward but it should be very easy to implement backwards moving.
I am using PagedDataSource To Paginate Repeater and it works fine but is there a way to highlight selected page number or make it bold. I tried css, itemcommand,and click event but no luck.
Thanks in advance
Repeater:
<asp:Repeater ID="repeaterPager" runat="server" OnItemCommand="repeaterPager_ItemCommand">
<ItemTemplate>
<asp:LinkButton CssClass="sayfaNo" ID="btnPage" CommandName="Page" CommandArgument="<%#Container.DataItem %>" runat="server">
<%# Container.DataItem %></asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
CodeBehind :
private void MakeleleriGetir()
{
SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings[0].ConnectionString);
SqlDataAdapter da = new SqlDataAdapter("SELECT p.PostID,p.Title,p.DateTime,p.PostShort,p.CategoryID,i.SmallFileName,c.CategoryName From Posts as p inner join Resimler as i ON p.PostID = i.PostID inner join Categories as c On p.CategoryID = c.CategoryID", cnn);
DataTable dt = new DataTable();
da.Fill(dt);
PagedDataSource pds = new PagedDataSource();
pds.DataSource = dt.DefaultView;
pds.AllowPaging = true;
pds.PageSize = 4;
pds.CurrentPageIndex = CurrentPage;
PageCount = pds.PageCount;
btnPrevious.Enabled = !pds.IsFirstPage;
btnNext.Enabled = !pds.IsLastPage;
if (pds.PageCount > 1)
{
repeaterPager.Visible = true;
ArrayList pages = new ArrayList();
for (int i = 0; i < pds.PageCount; i++)
{
{
pages.Add((i + 1).ToString());
}
}
repeaterPager.DataSource = pages;
repeaterPager.DataBind();
}
else
{
repeaterPager.Visible = false;

RepeaterPosts.DataSource = pds;
RepeaterPosts.DataBind();

protected int CurrentPage
{
get
{ // look for current page in ViewState
object o = this.ViewState["_CurrentPage"];
if (o == null)
{
return 0; // default to showing the first page
}
else
{
return (int)o;
}
}
set
{
this.ViewState["_CurrentPage"] = value;
}
}
public int PageCount
{
get
{
if (ViewState["_PageCount"] != null)
return Convert.ToInt32(ViewState["_PageCount"]);
else
return 0;
}
set
{
ViewState["_PageCount"] = value;
}
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
repeaterPager.ItemCommand += new RepeaterCommandEventHandler(repeaterPager_ItemCommand);
}
protected void repeaterPager_ItemCommand(object source, RepeaterCommandEventArgs e)
{
CurrentPage = Convert.ToInt32(e.CommandArgument) - 1;
MakeleleriGetir();
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
MakeleleriGetir();
}
protected void btnNext_Click(object sender, EventArgs e)
{
CurrentPage += 1;
MakeleleriGetir();
}
protected void btnPrevious_Click(object sender, EventArgs e)
{
CurrentPage -= 1;
MakeleleriGetir();
}
}
}
Logic:
Use ItemDataBound event and compare currentpage with current value of btnPage. You may use FindControl to get the current btnPage value.
Hope that helps!
protected void repeaterPager_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
//Enabled False for current selected Page index
LinkButton lnkPage = (LinkButton)e.Item.FindControl("btnPage");
if (lnkPage.CommandArgument.ToString() == (CurrentPage+1).ToString())
{
lnkPage.Enabled = false;
lnkPage.BackColor = System.Drawing.Color.FromName("#FFCC01");
}
}
Add New Row in GridView winform on Button Click.
Need to have single button in grid rather than DataGridViewButtonColumn
you can add it by using
GridView1.DataSource = datatable;
and then add new row by this
datatable.Rows.Add();
this will add new row and give control id into add().
use this
public partial class Form1 : Form
{
Button textBoxDgv1 = new Button();
Label labelDgv1 = new Label();
the next is on the Form_Load event
private void Form1_Load(object sender, EventArgs e)
{
labelDgv1.Text = "Delete";
labelDgv1.Height = 20;
labelDgv1.AutoSize = false;
labelDgv1.BorderStyle = BorderStyle.FixedSingle;
labelDgv1.TextAlign = ContentAlignment.MiddleCenter;
int Xdgv1 = this.dataGridView1.GetCellDisplayRectangle(2, -1, true).Location.X;
labelDgv1.Width = this.dataGridView1.Columns[2].Width + Xdgv1;
labelDgv1.Location = new Point(0, this.dataGridView1.Height - textBoxDgv1.Height);
this.dataGridView1.Controls.Add(labelDgv1);
and one more section is in dataGridView1_CellPainting
private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
int sum = 0;
for (int i = 0; i < this.dataGridView1.Rows.Count; i++)
{
if (dataGridView1.Rows[i].Cells[3].Value != string.Empty)
{
sum += Convert.ToInt32(this.dataGridView1[3, i].Value);
}
}
textBoxDgv1.Text = sum.ToString();
int Xdgvx = this.dataGridView1.GetCellDisplayRectangle(2, -1, true).Location.X;
labelDgv1.Width = this.dataGridView1.Columns[2].Width + Xdgvx;
labelDgv1.Location = new Point(0, this.dataGridView1.Height - textBoxDgv1.Height);
textBoxDgv1.Width = this.dataGridView1.Columns[3].Width;
Xdgvx = this.dataGridView1.GetCellDisplayRectangle(3, -1, true).Location.X;
textBoxDgv1.Location = new Point(Xdgvx, this.dataGridView1.Height - textBoxDgv1.Height);
}
I am trying to implement simple paging on my sharepoint webpart. I have a single news articles list which has some simple columns. I want to be able to have then five on a page and with some numerical paging at the bottom. I have gone through the net trying to understand splistitemcollectionposition but with no luck. If anyone can help please can you give me a simple code example or some guidanc
Many thanks

I would suggest using SPDataSource and a SPGridView, together they will implement paging and many other cool features with minimal or no code.
Use this a a guide for some of the classes/methods/properties you might need to use to get paging to work. Be aware that this code does not compile, i have just pulled together various code snippets that i have in my own list results framework, which includes paging, sorting, grouping and caching. It should be enough to get you started though.
public class PagedListResults : System.Web.UI.WebControls.WebParts.WebPart {
protected SPPagedGridView oGrid;
protected override void CreateChildControls() {
this.oGrid = new SPPagedGridView();
oGrid.AllowPaging = true;
oGrid.PageIndexChanging += new GridViewPageEventHandler(oGrid_PageIndexChanging);
oGrid.PagerTemplate = null; // Must be called after Controls.Add(oGrid)
oGrid.PagerSettings.Mode = PagerButtons.NumericFirstLast;
oGrid.PagerSettings.PageButtonCount = 3;
oGrid.PagerSettings.Position = PagerPosition.TopAndBottom;
base.CreateChildControls();
}
public override void DataBind() {
base.DataBind();
SPQuery q = new SPQuery();
q.RowLimit = (uint)info.PageSize;
if (!string.IsNullOrEmpty(info.PagingInfoData)) {
SPListItemCollectionPosition pos = new SPListItemCollectionPosition(info.PagingInfoData);
q.ListItemCollectionPosition = pos;
} else {
//1st page, dont need a position, and using a position breaks things
}
q.Query = info.Caml;
SPListItemCollection items = SPContext.Current.List.GetItems(q);
FilterInfo info = null;
string tmp = "<View></View>";
tmp = tmp.Replace("<View><Query>", string.Empty);
tmp = tmp.Replace("</Query></View>", string.Empty);
info.Caml = tmp;
info.PagingInfoData = string.Empty;
info.CurrentPage = oGrid.CurrentPageIndex;
info.PageSize = oGrid.PageSize;
if (oGrid.PageIndex == 0 || oGrid.CurrentPageIndex == 0) {
//do nothing
} else {
StringBuilder value = new StringBuilder();
value.Append("Paged=TRUE");
value.AppendFormat("&p_ID={0}", ViewState[KEY_PagingPrefix + "ID:" + oGrid.PageIndex]);
info.PagingInfoData = value.ToString();
}
int pagecount = (int)Math.Ceiling(items.Count / (double)oGrid.PageSize);
for (int i = 1; i < pagecount; i++) { //not always ascending index numbers
ResultItem item = items[(i * oGrid.PageSize) - 1];
ViewState[KEY_PagingPrefix + "ID:" + i] = item.ID;
}
oGrid.VirtualCount = items.Count;
DateTime time3 = DateTime.Now;
DataTable table = new DataTable("Data");
DataBindListData(table, items);
this.oGrid.DataSource = table;
this.oGrid.DataBind();
this.oGrid.PageIndex = oGrid.CurrentPageIndex; //need to reset this after DataBind
}
void oGrid_PageIndexChanging(object sender, GridViewPageEventArgs e) {
oGrid.PageIndex = e.NewPageIndex;
oGrid.CurrentPageIndex = oGrid.PageIndex;
}
}
public class FilterInfo {
public string Caml;
public string PagingInfoData;
public int CurrentPage;
public int PageSize;
}
public class SPPagedGridView : SPGridView {
protected override void InitializePager(GridViewRow row, int columnSpan, PagedDataSource pagedDataSource) {
pagedDataSource.AllowCustomPaging = true;
pagedDataSource.VirtualCount = virtualcount;
pagedDataSource.CurrentPageIndex = currentpageindex;
base.InitializePager(row, columnSpan, pagedDataSource);
}
private int virtualcount = 0;
public int VirtualCount {
get { return virtualcount; }
set { virtualcount = value; }
}
private int currentpageindex = 0;
public int CurrentPageIndex {
get { return currentpageindex; }
set { currentpageindex = value; }
}
}
check out my post on how to page using SPListItemCollectionPosition, I did a component to page over lists, maybe it can help -> http://hveiras.wordpress.com/2011/11/07/listpagert-using-splistitemcollectionposition/
