I have a Button in datagridview and its text is Start so when I Click on it the text now should be Stop and when I click again the text should be Start.
So i have written code but its didnt work for me
private void dgvCampaign_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
if (e.Control is Button)
{
Button btn = e.Control as Button;
if(btn.Text=="Start")
btn.Text = "Stop";
else
btn.Text = "Start";
}
}
try to use CellContentClick event
private void dataGridView2_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex == 2)
{
if (dataGridView2[e.ColumnIndex, e.RowIndex].EditedFormattedValue.ToString().Length > 0)
{
if (dataGridView2[e.ColumnIndex, e.RowIndex].EditedFormattedValue.ToString() == "Start")
{
dataGridView2[e.ColumnIndex, e.RowIndex].Value = "Stop";
}
else
{
dataGridView2[e.ColumnIndex, e.RowIndex].Value = "Start";
}
}
else
dataGridView2[e.ColumnIndex, e.RowIndex].Value = "Start";
}
}

I have a windows form it has 8 textboxes , 3 combobox and a radio button.
I am using this code but it does not work.
I put the beakpoint and checked the control does not go inside if(Cnt is TextBox) It is evaluating to false. I am keeping all the controls in the panel. May be because of this I am having a problem
private void button1_Click(object sender, EventArgs e)
{
foreach (Control cnt in this.Controls)
{
if (cnt is TextBox)
{
if (cnt.Text == "")
{
MessageBox.Show("TextBox is Blank.");
cnt.BackColor = Color.Pink;
}
}
else if (cnt is ComboBox)
{
ComboBox cmb = (ComboBox)cnt;
if (cmb.SelectedItem == null)
{
MessageBox.Show("Combox is not Selected.");
cnt.BackColor = Color.Plum;
}
}
}
}
I tried to get the code below working, but to no avail.
I have to make a login window, and except from the Log in button I want by pressing the Enter key in password textbox the result to be the same. C# 2010.
private void button1_Click(object sender, EventArgs e)
{
int ok=0;
if (textBox1.Text == "administrator" && textBox2.Text == "administrator")
{
ok = 1;
this.Hide();
Admin admin = new Admin();
admin.ShowDialog();
}
if (textBox1.Text == "jucator" && textBox2.Text == "jucator")
{
ok = 1;
this.Hide();
}
if (ok == 0)
{
label2.Text = "nume user sau parola incorecta";
label2.Visible = true;
}
}
private void textBox2_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
button1_Click(this, new EventArgs());
}
}
You should use the KeyUp event It's more reliable in you case.
Then check for the pressed key.
e.g.:
private void textBox2_KeyUp(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
//DoLogin... in your case it would be
button1_Click(null,null);
e.Handled = true;
}
else
{
e.Handled = false;
}
}
On a side note: I really discourage you to use that Log In method, comparing strings to a hardcoded strings is really a waste, there're better scenarios specially in an environment where you have multiple users Otherwise why would you require a login?
How to change text of a cell at runtime in XtraReport?
I am using "DevExpress v2011 vol 1".
I have a few cells and I can change their text one by one using PreviewClick event as below.
private void _cell_PreviewClick(object sender, PreviewMouseEventArgs e)
{
e.Brick.Text = "aaabbbccc"; e.PreviewControl.Refresh();
}
But, in that event I need to change text of other cells simultaneously. I tried below and got no luck
private void _cell_PreviewClick(object sender, PreviewMouseEventArgs e)
{
e.Brick.Text = "aaabbbcc";
otherCell1.Text = "rrrttcwwww"
e.PreviewControl.Refresh();
}
Best Regards,
Orgil.D
You can handle the DataSourceRowChanged event of the XtraReport Class
private void rpt_DataSourceRowChanged(object sender, DataSourceRowEventArgs e)
{
MyClass xx = bidingSource[e.CurrentRow] as MyClass ;
if (string.IsNullOrWhiteSpace(xx.WorkDescription))
{
xrTableCell25.Visible = false;
xrTableRow3.Visible = false;
xrTableCell25.Text = "456";
}
else
{
xrTableCell25.Visible = true;
xrTableRow3.Visible = true;
xrTableCell25.Text = "123";
}
}
I have a Page which a FormPanel(there's a ComboBox in it) and a TreePanel(has a default root node) in it and open ViewState.
I set a value to ComboBox in GET.
When i GET the page the TreePanel's Store send a POST request(store read) before FormPane rendered in client,in this POST request the fromdata has no info about FormPane.
in the POST request recover the ComboBox.Value from ViewState,but in ComboBoxBase.LoadPostData() Ext.Net get value from formdata and cover ComboBox.Value without precondition
it's ComboBoxBase.LoadPostData() code
protected override bool LoadPostData(string postDataKey, NameValueCollection postCollection)
{
this.HasLoadPostData = true;
string text = postCollection[this.UniqueName];
string state = postCollection[this.ValueHiddenName.IsNotEmpty() ? this.ValueHiddenName : ("_" + this.UniqueName + "_state")];
this.SuspendScripting();
this.RawValue = text;
this.Value = text;
this.ResumeScripting();
if (state == null && text == null)
{
return false;
}
if (!this.EmptyText.Equals(text) && text.IsNotEmpty())
{
List<ListItem> items = null;
if (this.SimpleSubmit)
{
var array = state.Split(new char[] { ',' });
items = new List<ListItem>(array.Length);
foreach (var item in array)
{
items.Add(new ListItem(item));
}
}
else if(state.IsNotEmpty())
{
items = ComboBoxBase.ParseSelectedItems(state);
}
bool fireEvent = false;
if (items == null)
{
items = new List<ListItem>
{
new ListItem(text)
};
/*fireEvent = this.SelectedItems.Count > 0;
this.SelectedItems.Clear();
return fireEvent;
*/
}
foreach (var item in items)
{
if (!this.SelectedItems.Contains(item))
{
fireEvent = true;
break;
}
}
this.SelectedItems.Clear();
this.SelectedItems.AddRange(items);
return fireEvent;
}
else
{
if (this.EmptyText.Equals(text) && this.SelectedItems.Count > 0)
{
this.SelectedItems.Clear();
return true;
}
}
return false;
}
Look at Line 5 to 11,why not change like this
string text = postCollection[this.UniqueName];
string state = postCollection[this.ValueHiddenName.IsNotEmpty() ? this.ValueHiddenName : ("_" + this.UniqueName + "_state")];
this.SuspendScripting();
this.RawValue = text;
this.ResumeScripting();
if (state == null && text == null)
{
return false;
}
this.SuspendScripting();
this.Value = text;
this.ResumeScripting();

We committed the change to the SVN trunk. It will go to the next release (v2.3).
The change is similar to your one, but we decided not to change RawValue as well. Thank you for the report and suggested fix.
Fix (ComboBoxBase LoadPostData)
protected override bool LoadPostData(string postDataKey, NameValueCollection postCollection)
{
this.HasLoadPostData = true;
string text = postCollection[this.UniqueName];
string state = postCollection[this.ValueHiddenName.IsNotEmpty() ? this.ValueHiddenName : ("_" + this.UniqueName + "_state")];

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>

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");
}
