Hello,

When i have a row in edit mode and try to expand, I cant retrieve the parentitem's column value.

In RadGrid1_DetailTableDataBind:

when i do e.DetailTableView.ParentItem("BondID").Text) it returns " "

This works fine if the row is not in edit mode.

dynamic radgrid header name produce odd change of line

Hello,
I'm creating dynamic radgrid with dynamic columns names. The names all come from the database and can be either in English or in French. When a column's name contain a french character such as é à è ê ç... or if it contain ' or - a space is automatically added after the character witch odd result such as:
"Remplaç
ant"
or
"Anné
e"
or
"sous
-
code"
I tried to prevent text wraping this way:
grid.HeaderStyle.Wrap = false;
This way I don't get odd wrapping, but I still get space after those character, so it now looks like:
"Remplaç ant"
"Anné e"
"sous- code"
It's a little bit better but far from acceptable. The data binding is done this way (table been a DataTable):
grid.DataSource = table;
I tried to use Server.HtmlEncode() to make sure that the string is in the right format, but no luck... Since I'm using a DataTable, I don't think I can use TextBlock. Any idea?

Thanks,
LP

Problems inheriting GridTemplateColumn

when i try to replace GridTemplateColumns with my customFilteredGridTemplateColumns the RadGrid isnt shown due to many bugs which seems irrelevant to Rad objects at all. what am i doing wrong? here is my implementation:

public class CustomFilteredGridTemplateColumn : GridTemplateColumn

{

public override GridColumn Clone()

{

return base.Clone();

}

protected override void SetupFilterControls(System.Web.UI.WebControls.TableCell cell)

{

base.SetupFilterControls(cell);

cell.Controls.RemoveAt(0);

cell.Controls.AddAt(0,

new TextBox());

}

public override bool SupportsFiltering()

{

return true;

}

protected override string GetFilterDataField()

{

return this.DataField;

}

protected override void SetCurrentFilterValueToControl(TableCell cell)

{

base.SetCurrentFilterValueToControl(cell);

(cell.Controls[0]

as TextBox).Text = this.CurrentFilterValue;

}

protected override string GetCurrentFilterValueFromControl(TableCell cell)

{

return (cell.Controls[0] as TextBox).Text;

}

}

RadGrid Filter controls hang

I have a RadGrid with a date column and several text columns and filtering enabled. When I select a date to be filtered, type text in one of the text fields and then select another filter field, the grid filters properly, but I can no longer type in the filter text fields.

I am using RadControls for ASP.NET Ajax Q2 2009.

Any suggestions?

My grid code is:

    
            <telerik:RadGrid ID="ShipmentHistoryGrid" runat="server" Skin="Web20" OnNeedDataSource="OnShipmentHistoryGridNeedDataSource"

editform - determine which mode WebUserControl is in?

hello,

im on an older version of RadControls for ASP.NET AJAX ("2009.2 826") but i think the answer to my question should be pretty straight-forward.

im using a RadGrid that uses WebUserControl for the grid's EditFormType. This .ascx form is displayed for Insertion and Update operations. my question -- in the user control's code-behind, how can i tell which mode the code is being executed as? i use this to show different things if the user is performing an Insert vs. an Update.

currently i use this code in the user control's .ascx.cs:

private void Page_PreRender(object sender, EventArgs e)

{

//this is the only way i know how to check what mode this grid control is operating in.

bool isGridInsertion = Object.ReferenceEquals(this.DataItem.GetType(), new GridInsertionObject(new ArrayList()).GetType() );

if (isGridInsertion != true)

//we check this because the below int assignment breaks on a grid insertion (since ProductTypeID has no value during our Insert form, only populated on Edit)

{

int productTypeID = (int)DataBinder.Eval(this.DataItem, "ProductTypeID");

// do stuff

}

...is there a better way than doing the Object.ReferenceEquals on the DataItem's type (comparing it to a GridInsertionObject's type) ?

thanks!
matt

I would like to propose to the visitor a value in a RadTextBox calculated on value inserted by this visitor in another RadTextBox.
But how can I get access to these fields in js ?
In .Net code behind no problem.. but I don't know how to do that on client side.

Can someone help me on this ?

Radwindow not opening in RadGrid button column click event

Hi Telerik Team,

This problem is related with opening a RadWindow. I have a RadGrid with a button column and need to open an Radwindow within its click event (command event). So far, this has not been a problem for me, since I had call the RadWindow mostly in

button click event of a button. (I did it like -- > RadWindow1.VisibleOnPageLoad=true ).

But when I try to do the same thing the window is not shown (pop-up). Can you please tell me the reason?

Note: The reason for me to open/show the RadWindow in code behind using "RadWindow1.VisibleOnPageLoad=true" is, I need to

to do some validations to get the decision whether to open it or do another operation.

Thanks,

Dilip Nilanka
