Hi,

When I click the delete button on my RadGrid, I get this error:

I found that this data format string is the culprit:

<telerik:GridBoundColumn DataField="Price" DataFormatString="{0:c}" DataType="System.Decimal"
            HeaderText="Price" SortExpression="Price" UniqueName="Price">
        </telerik:GridBoundColumn>

Here is all of my code:


This also happens with the Numeric Column type. What can I do to resolve this error without removing the data format string?

Hi!

Hi,

I have binded some data to radcombobox during pageload. This is rendered as multicolumned radcomboxbox. I need to add some more data dynamically after user inputs the value.

Please let me know how to achieve ths.
The below is what I have implemented but the data is not getting inserted in the dropdow

public

 

class ItemTemplate : ITemplate

 

{

 

public void InstantiateIn(Control container)

 

{

 

Literal lit = new Literal();

 

lit.Text =

"<div class='cmb_rdFnt cmb_ltFlt'>" + "ABC" + "</div> <div class='cmb_rdFnt cmb_ltFlt cmb_sp20'>"+"DEF"+"</div>"+"<div class='cmb_rdFnt cmb_ltFlt cmb_sp20'>"+"GHI"+"</div>";

 

container.Controls.Clear();

container.Controls.Add(lit);

}
// Page_load evenet

 

if

 

(!Page.IsPostBack)

 

{

 

PaymentSelectionData pmtSelData;

 

 

for (int i = 0; i < 5; i++)

 

{

pmtSelData =

new PaymentSelectionData();

 

pmtSelData.paymentTypeDesc =

"desc1" + i.ToString();

 

lstPmtSel.Add(pmtSelData);

}

RadComboBox1.DataValueField =

"refVal";

 

RadComboBox1.DataTextField =

"paymentTypeDesc";

 

RadComboBox1.DataSource = lstPmtSel;

RadComboBox1.DataBind();

 

}

 

 

 

 

 

else

 

 

 

 

 

{

 

 

 

 

 

RadComboBoxItem item = new RadComboBoxItem();

 

item.Attributes.Add(

"info", "Hello");

 

RadComboBox1.Items.Add(item);

 

ItemTemplate i1 = new ItemTemplate();

 

i1.InstantiateIn(item);

RadComboBox1.DataBind();

 

}

Hello.I have used ContentAreaCssFile but i see that it's not applied in the preview area.
Any ideas?

Hey..

I'm using two GridDropDownColumns on my RadGrid.. Every time I add new records, it seems that the selected value returns a null value. Textboxes are okay, they work fine. Error's just with the dropdown values..

I've tried searching forums on topics like this but none of them worked..

Would really really appreciate the help.

Thank you.

Need to idiot proof my editor so that on submit, it runs the spell checker.  Problem is that I can't find any javascript call to run the Editor's spell checker.  Please help.

Hi, I recently bought Telerik controls.  I am getting performance issue with radgrid.

1. I implemented paging to the radgrid with 6000 records. And i created viewall option on rg402_ItemCreated to the radcombo.  When i select viewall its taking 20 sec to bind the data to the grid and after that the brower gets stuck( both Firefox 3.6.4 and IE7)  and displaying the error(Please find attached Image). Is there anyway to change the viewall option code to get the data fast. or is there anyway to improve the performance and decrease the time of records binding.

Here is my code.

.aspx code
.cs fine

I am using Subgrid (NestedTemplate) inside a Radgrid. As per the current design, ">" image is displaying for expand/collapse when we want see the subgrid content.

Is it possible to replace that ">" image with "View" text instead as a Linkbutton.

thanks

I have an application where the user should be able to drag nodes from a treeview to a form. It doesn't really matter what element the node gets dragged to, as long as it is dropped in the form area.
To detect where a node was dropped, I use the OnClientNodeDropping event. However, it seems that this event only fires sometimes when the receiving element is a RadTextBox! In about half of the cases, it seems like the release of the mouse button is not detected, and the user is forced to click to fire the OnClientNodeDropping event.

I have here a simple example that shows the problem. To reproduce, place the cursor in the textbox, and drag a node from the tree view to the textbox (possibly repeat). This is tested on FireFox 3.6.4.


I hope someone can help me. It seems like the problem never appears if I just use a normal <asp:textbox> control, but I really would like to keep the RadTextBox controls on the page.

Thanks,

Ulrik Rasmussen
