Hi,

I am using RadGrid and doing a simple data binding to bind to a list. The enableviewstate is set to true. But the grid does not populate data after a postback. Am I doing any thing wrong.

Select value from RadGrid onmouseover

Hello Telerik Team,

I would like to first thank you for a constant and high quality product.

I have a RadGrid that is grouped with custom fields, I am currently opening RadWindows from the ImageButton click events like so:

protected void Play_Click(object sender, ImageClickEventArgs e)

{

Geek.XTV7_Time_Start = DateTime.Now.ToString();

string sql = "";

var dt = new DataTable();

sql += " Select ISNull( XTV7_VideoHits, 0) AS XTV7_VideoHits From Xtrain.XTV7_2_Videos WHERE (XTV7_Videos_ID=" + Geek.XTV7_Videos_ID.ToString() + ")";

dt = data.GetDataTable(sql);

Geek.XTV7_VideoHits = (Int32.Parse(dt.Rows[0]["XTV7_VideoHits"].ToString()) + 1).ToString();

VidHit();

RadAjaxManager1.ResponseScripts.Add("radopen('Forms/View/VideoViewer.aspx','RadWindow1')");

}

to open a RadWindow (depending on what button, as each button has its own windows via a RadWindow Manager) after passing a session variable via my session handler Geek.XTV7_Videos_ID from the SelectedValue. (this code is used to get the id and pass it to the session variable:

protected void RadGrid_ItemCommand(object source, GridCommandEventArgs e)

{

if ((e.Item is GridDataItem) && (e.CommandName == "Select"))

{

var item = (GridDataItem)e.Item;

string gvDataKey = item.GetDataKeyValue("XTV7_Videos_ID").ToString();

Geek.XTV7_Videos_ID = gvDataKey;

}

)

Then on RadWindowClose() there is a value written to the DataBase to reflect the hits, the window close method initiates the folowing code to refresh the grid and send update command to the DB:

videoselector.ascx.cs

#region Ajax Manager Request

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

switch (e.Argument)

{

case "closed":

UpdateView();

RadGrid1.Rebind();

break;

}

#endregion

videoselector.ascx

function onClose() {

$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("closed");

}

function RowSelected(row) {

}

sorry for the long intro but I need to be sure that the environment is understood.

THE PROBLEM:
we need to be able to pass a variable to Geek.XTV7_Videos_ID on mouse over and refresh or instantiate an AJAX request on the panel shown in the attached image (without breaking existing methods and events).
How would I go about this?

Thank you very much in advance.

get label control value from radgrid

Hi,

Can someone help me figure out how to get a label control text value from grid item template column?

<telerik:GridTemplateColumn DataField="Amount" HeaderText="Amount" UniqueName="Amount">

<ItemStyle BorderStyle="NotSet" CssClass="test" HorizontalAlign="Right" Width="75px" />

<HeaderStyle HorizontalAlign="Center" Width="85px" />

<ItemTemplate>

<asp:Label ID="lblAmount" runat="server" Text='<%# Eval("Amount") %>'

Width="75"></asp:Label>

</ItemTemplate>

<EditItemTemplate>

<asp:Label ID="lblAmount" runat="server" Text='<%# Eval("Amount") %>'

Width="75"></asp:Label>

</EditItemTemplate>

</telerik:GridTemplateColumn>

Label amount = (Label)item.FindControl("lblAmount");

double? amount= (item["Amount"].FindControl("lblAmount") as Label).Text;

I've tried both ways and neither seems to work. Thanks in advance.

Line: 8 Error: Object doesn't support this property or method

I am getting the following Javascript error:

Line: 8
Error: Object doesn't support this property or method

the following line of code is shown when debugging the code.

!v&&b.length>1&&d(b,"")>-1&&(j=RegExp(this.source,e.replace.call(c(this),"g","")),e.replace.call(a.slice(b.index),j,function(){for(var a=1;a<arguments.length-2;a++)arguments[a]===void 0&&(b[a]=void 0)

The javascript file that is purporting the error is in "itn.js".

I am getting this error when a Rad combo box is used as an editor for a column and when I click the drop down button to display the list of items within the drop down. Now I get the error only in IE Version 8.0.7601.17514 and not the other browsers. I checked to see if it was something in my code but its not. I am also receiving the error from your Demo site on the following page:

http://demos.telerik.com/aspnet-ajax/treelist/examples/columns/columntypes/defaultcs.aspx

it is on the second treelist control where the "Title Of Courtesy" contains a RadComboBox. Again when I click the drop down button on the control it throws the above javascript error. It never drops down the list of items on the control.

Any help on this I would greatly appreciate it.

Thanks

Problem with events

Hello,

I have a problem with my treeview events :

Normaly, the clickNode event is fired before the dataBound event.
But sometimes, it is the dataBound event which is fired before the clickNode.

Is there a solution to force clickNode first?
