Is it possible to change the default option all column filters? I'm pretty sure I can accomplish this with some JavaScript, but I'd like to know if there's any way within the Acumatica framework to change this.
The answer will be no. The filter is inside the PX.Web.UI.dll in the PXGridFilter class which is an internal class. The property that you are interested in is the Condition.
The value is set inside one of the private methods of the PXGrid class. The code of the method is below:
private IEnumerable<PXGridFilter> ab()
{
List<PXGridFilter> list = new List<PXGridFilter>();
if (this.FilterID != null)
{
Guid? filterID = this.FilterID;
Guid guid = PXGrid.k;
if (filterID == null || (filterID != null && filterID.GetValueOrDefault() != guid))
{
using (IEnumerator<PXResult<FilterRow>> enumerator = PXSelectBase<FilterRow, PXSelect<FilterRow, Where<FilterRow.filterID, Equal<Required<FilterRow.filterID>>, And<FilterRow.isUsed, Equal<True>>>>.Config>.Select(this.DataGraph, new object[]
{
this.FilterID.Value
}).GetEnumerator())
{
while (enumerator.MoveNext())
{
FilterRow row = enumerator.Current;
string dataField = row.DataField;
PXCache pxcache = PXFilterDetailView.TargetCache(this.DataGraph, new Guid?(this.FilterID.Value), ref dataField);
if (this.Columns[row.DataField] != null)
{
List<PXGridFilter> list2 = list;
int valueOrDefault = row.OpenBrackets.GetValueOrDefault();
string dataField2 = row.DataField;
string dataField3 = row.DataField;
int value = (int)row.Condition.Value;
object value2 = pxcache.ValueFromString(dataField, row.ValueSt);
string valueText = row.ValueSt.With((string _) => this.Columns[row.DataField].FormatValue(_));
object value3 = pxcache.ValueFromString(dataField, row.ValueSt2);
string value2Text = row.ValueSt2.With((string _) => this.Columns[row.DataField].FormatValue(_));
int valueOrDefault2 = row.CloseBrackets.GetValueOrDefault();
int? #operator = row.Operator;
int num = 1;
list2.Add(new PXGridFilter(valueOrDefault, dataField2, dataField3, value, value2, valueText, value3, value2Text, valueOrDefault2, #operator.GetValueOrDefault() == num & #operator != null));
}
}
return list;
}
}
}
if (this.FilterRows != null && this.FilterRows.Count > 0)
{
for (int i = 0; i < this.FilterRows.Count; i++)
{
PXFilterRow row = this.FilterRows[i];
list.Add(new PXGridFilter(row.OpenBrackets, row.DataField, row.DataField, (int)row.Condition, row.Value, row.Value.With(delegate(object _)
{
if (this.Columns[row.DataField] == null)
{
return _.ToString();
}
return this.Columns[row.DataField].FormatValue(_);
}), row.Value2, row.Value2.With(delegate(object _)
{
if (this.Columns[row.DataField] == null)
{
return _.ToString();
}
return this.Columns[row.DataField].FormatValue(_);
}), row.CloseBrackets, row.OrOperator));
}
}
return list;
}
UPDATE
The below JS code allows you to change the condition of the last set filter:
px_all.ctl00_phG_grid_fd.show();
px_all.ctl00_phG_grid_fd_cond.items.items[7].setChecked(true);
px_all.ctl00_phG_grid_fd_ok.element.click();
px_all.ctl00_phG_grid_fd_cond.items.items[7].value "EQ"
px_all.ctl00_phG_grid_fd_cond.items.items[8].value "NE"
px_all.ctl00_phG_grid_fd_cond.items.items[9].value "GT"
px_all.ctl00_phG_grid_fd_cond.items.items[13].value "LIKE"
px_all.ctl00_phG_grid_fd_cond.items.items[14].value "LLIKE"
px_all.ctl00_phG_grid_fd_cond.items.items[15].value "RLIKE"
px_all.ctl00_phG_grid_fd_cond.items.items[16].value "NOTLIKE"
px_all.ctl00_phG_grid_fd_cond.items.items[18].value "ISNULL"
px_all.ctl00_phG_grid_fd_cond.items.items[19].value "ISNOTNULL"
I am using normal mvc textboxfor on strong view, I have created custom validation attribute (the detailed code explained below).
On form submit everything works fine. In case if validation fails by natural it shows error message as configured.
Now when I enter the correct value inside text box I expect the error message to be vanished automatically but this does not happen until I post the form
JS File
$.validator.addMethod('validaterequiredif', function (value, element, parameters) {
var id = parameters['dependentproperty'];
var clickValue = $("input[name=" + id + "]:checked").val();
// get the target value (as a string,
// as that's what actual value will be)
var targetvalue = parameters['targetvalue'];
if (clickValue == targetvalue) {
if (value == null) {
return false;
}
else {
return $.validator.methods.required.call(
this, value, element, parameters);
}
}
else {
return true;
}
});
$.validator.unobtrusive.adapters.add(
'validaterequiredif',
['dependentproperty', 'targetvalue'],
function (options) {
options.rules['validaterequiredif'] = {
dependentproperty: options.params['dependentproperty'],
targetvalue: options.params['targetvalue']
};
options.messages['validaterequiredif'] = options.message;

i'm currently writing an application with a parent class named 'Vehicle' and two children classes named 'Car' and 'Truck'. My problem is that I would like to search through the full list of Vehicles and return only each car, or each truck depending on what object is placed into a method. Right now I have had to write a method for ach search term such as below:
public string searchCarsByName(string nameString)
{
string carNames = "";
foreach (Car car in Vehicles.OfType<Car>())
{
if (car.Name.Contains(nameString))
{
carNames += car.ToString();
}
}
if (carNames == "")
{
return "No cars found";
}
else
{
return carNames;
}
}
public string searchTrucksByName(string nameString)
{
string truckNames = "";
foreach (Truck truck in Vehicles.OfType<Truck>())
{
if (truck.Name.Contains(nameString))
{
truckNames += name.ToString();
}
}
if (truckNames == "")
{
return "No vehicle found";
}
else
{
return truckNames;
}
}
My only problem is that the names isn't the only way I would like to search, so for each search I am going to perform then I will have to write two methods. What i'm looking for is a way to pass in an Object to the method, and then dependent on the object it will append the necessary details to the string such as below:
public string searchVehiclesByName(Vehicle nameString)
{
string vehicleNames = "";
if(Vehicle.Type == car)
{
foreach (Car car in Vehicles.OfType<Car>())
{
if (car.Name.Contains(nameString))
{
vehicleNames += car.ToString();
}
}
}
else
{
foreach (Truck truck in Vehicles.OfType<Truck>())
{
if (truck.Name.Contains(nameString))
{
vehicleNames += truck.ToString();
}
}
}
if (vehicleNames == "")
{
return "No vehicles found";
}
else
{
return vehicleNames;
}
}
}
Essentially what I need is a way to pass in a parent object and check if an object is of a certain child type before creating the resultant string, rather than having to pass each individual type of child object into a method to get the results I want.
Thank you in advance.
Please have a look at this: Type Checking: typeof, GetType, or is?
public string searchVehiclesByName(Vehicle vehicle)
{
string vehicleNames = "";
if(vehicle.GetType() == typeof(Car))
{
foreach (Car car in Vehicles.OfType<Car>())
{
if (car.Name.Contains(nameString))
{
vehicleNames += car.ToString();
}
}
}
else
{
foreach (Truck truck in Vehicles.OfType<Truck>())
{
if (truck.Name.Contains(nameString))
{
vehicleNames += truck.ToString();
}
}
}
if (vehicleNames == "")
{
return "No vehicles found";
}
else
{
return vehicleNames;
}
}
Hope this helps.
I am very new to Sharepoint development. I have the following code that I need to have display the list items by targeted audience. I know I am suppose to add something like this
AudienceLoader audienceLoader = AudienceLoader.GetAudienceLoader();
foreach (SPListItem listItem in list.Items)
{
// get roles the list item is targeted to
string audienceFieldValue = (string)listItem[k_AudienceColumn];
// quickly check if the user belongs to any of those roles
if (AudienceManager.IsCurrentUserInAudienceOf(audienceLoader,
audienceFieldValue,
false))
But I have no idea where to place it in my code below. Please I would appreciate any of your advise.

You can put the code in CreateChildControls() method.
I have a text like this
"You are advised to grant access to these settings only if you are sure you want to allow this program to run automatically when your computer starts. Otherwise it is better to deny access."
and i have 3 selections,
1. StartIndex = 8, Length = 16 // "advised to grant"
2. StartIndex = 16, Length = 33 //"to grant access to these settings"
3. StartIndex = 35, Length = 26 // "these settings only if you"
i need to insert span tags and highlight selections, and intersections of words should be highlighted in different color,
result should be something like this
"You are <span style= 'background-color:#F9DA00'>advised </span> <span id = 'intersection' style= 'background-color:#F9DA00'>to grant </span> <span style= 'background-color:#F9DA00'>advised </span> <span style= 'background-color:#F9DA00'>access to </span>
<span id = 'intersection' style= 'background-color:#F9DA00'>these settings</span>
<span style= 'background-color:#F9DA00'>only if you </span> sure you want to allow this program to run automatically when your computer starts. Otherwise it is better to deny access."
please help me to sort this out, i have been trying to figure-out a logic for a long time now and no luck so far
Markup comment: IDs need to be unique. Make them classes instead: class="intersection".
finally manage to find a solution on my own, hope this help someone also in the future
