problem wiht setting values on update
Hi,

I'm having a problem when I try to set some value on a field. I have a GridTemplateColumn with a RadComboBox, and if some value in specific is selected a windows shows up and return a value. If I'm on insert mode I can put this value on the field whit this code

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
   GridDataItem item = (GridDataItem)combo.NamingContainer;
   HtmlInputText valor = (HtmlInputText)item.FindControl("Valor");
   valor.Value = e.Argument;
}

the combo variable is global and I obtain the value with this

protected void Op_OnSelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
{   
   combo = (RadComboBox)sender;
}

this code works fine, but my problem comes when I try to update because doesn't change the value that the window returned.
I have this method
protected void ItemDataBound_condicion(object sender, GridItemEventArgs e)
{
     if (e.Item.IsInEditMode && e.Item is GridDataItem)
     {
        GridEditableItem item = e.Item as GridEditableItem;
        RadComboBox operador = (RadComboBox)item.FindControl("Operador");
        combo = operador;
        if (operador.SelectedValue == "En la lista" || operador.SelectedValue == "No en la lista")
        {
          valor = (HtmlInputText)item.FindControl("Valor");
          valor.Attributes.Add("onclick", "OnClientClick(valor.Value);
        }
    }
 }

I'm setting the combo to the RadComboBox of the row, and use the same code of the method RadAjaxManager1_AjaxRequest, but it doesn't work, only works when I change the value of  'Operador' but when I click the field 'Valor' doens't works.

Am I doing something wrong??

Thanks in advance.

visual studio hanging on getting web.config
I upgraded to the newest release of the ajax toolkit.  After the project is updated, I can't open the project anymore with visual studio 2010.  When opening, it hangs on "getting web.config" file.  If I delete the web.config file, it opens without a problem.  Has anybody else experienced this issue?

Enable/Disable RadTextBox with Client API
Hello,

For some reason, the RadTextBox is not re-enabling.  I initially disable it with this code:

notLinkingTextBox.set_value("");
notLinkingTextBox.set_enabled(false);

Later on, a process checks to see whether a radcombobox has a particular value, and enables or disables the textbox with:

if (sender.get_value() == "5") {
	textbox.enable();
}
else {
	textbox.set_value("");
	textbox.disable();
}

I've also tried:

if (sender.get_value() == "5") {
	textbox.set_enabled(true);
}
else {
	textbox.set_value("");
	textbox.set_enabled(false);
}

But none of these are bringing them back... so what is the way to reenable the textbox?  I verified it is hitting the enable code (enable() method or set_enabled(true) method), so what do I need to do?

Thanks.

Grid binding is too slow when retrieving large database
Hi,

I am working on a project that have developed by previous developers. In this project, there is a RadGrid which is used to manage the members. The member details are fetched from the database using a stored procedure and is binding it to the RadGrid. When the number of members is large, it takes a very long time to load the grid. I have checked the code and found that the ItemDatabound event of the grid creates the problem. There are some checking in this event which required to load the values in the grid. The html part of the grid is :

 

<telerik:RadGrid ID="radGvMembers" runat="server" AllowPaging="True" AutoGenerateColumns="false"
                            GridLines="None" OnNeedDataSource="radGvMembers_NeedDataSource" AllowAutomaticDeletes="True"

How can we speed up the execution of the page? Please advice me.

How to cause postback on filtering?
I have a RadGrid set up for filtering.  I would like the page to postback (preferably via ajax) when a new filter is applied by the user.  I've searched through the documentation and there doesn't seem to be any sort of "OnFilterApplied" or "OnFilterApplying" event.  How can I accomplish this?

Further reduce WebResource.axd calls
Even with a script manager I'm still getting WebResource.axd requests for js files that include:
  • function WebForm_FindFirstFocusableChild(control)
  • function WebForm_PostBackOptions
Any idea how I can get those documents handled by the script manager?

Thanks!

how to update grid items after update command button clicked
I have a radgrid using the automatic operations (insert/update/delete).  I have two columns in the grid called "ModifiedBy" and "DateCreated" When in edit mode and after the update button is clicked, I need to update the values of those columns for the selected item with the current logged in user and current date.  I know how to get the logged in user and date but I'm not clear on how to  bind that data back to the database.

How can this be done in the code-behind using vb.net?  I've tried to use e.Item.OwnerTableView.PerformUpdate() but I'm not sure how to do it.  Is there a better way to accomplish this?  Any help would be greatly appreciated.
