Telerik team, I have been looking for a solution for this issue but cant find the right answer.
I dont know how to access to my template´s controls. I saw in the commanditem is too early to get the controls, but as I said before on my post, one I load the page I set on true the addrecord so it opens with the adding new record and also on my template I need to bind radcombox.
Please if someone can help me. I just really confuse and i have search on the telerik demos but dont appears this case and also in the forum. Please let me know how could I do this:

On my grid I have a template form, with just a few fields, not all, I need to bind some combos on the edit form, and when i insert and update I stored these values on a data structure which I bind my grid (a list) and after insert update or delete I save all to the data base. Please someone can give me a hint!

Best regards,
Thanks!

Hi,

I suppose you want to access RadTextBox in Insert mode. here is the sample code.
C#:

protected void RadGridExpensesLines_InsertCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
 GridEditFormInsertItem editedItem = e.Item as GridEditFormInsertItem;
 RadTextBox txt= (RadTextBox)editedItem.FindControl("RadTextBoxArticleName");
}

Thanks,
Shinu

Hello,

Are you used EditForms as EditMode ? (if yes then please provide your code.)

like :

<MasterTableView EditMode="EditForms">

I am ussing EditForm.
I finally resolve it, it was because of the typecast, I made a typecast to asp controls instead rad controls.

line.Article = (container.FindControl(

 

"RadTextBoxArticle") as RadTextBox).Text;

But I have a problem now, as I said I use EditForm, but when I am trying to edit a row, the items I want to show them on its corresponding controls. For example: if I select row one and it has Article, Amount, IVA, I want the values will be show in the controls, but when I am trying to edit, are blanck.

This is my Template form:

 

 

 

<EditFormSettings EditFormType="Template">

 <FormTemplate>

Hi,

You can bind the text as shown below.
aspx:

<telerik:RadTextBox ID="RadTextBox1" runat="server"  Text='<%#Bind("ID")%>'></telerik:RadTextBox>

Thanks,

Hi Shinu
I tried with this but in the case of the radcombobox says databinding methods such as Eval, Xpas, and bind can only be used in the context of a databound cotrol: This is how I bind my combo: I populate my combobox in OnItemDataBond. Hope you can help me! Thanks!!!

<

 

 

telerik:RadComboBox ID="RadComboBoxTax" runat="server" DataValueField="Id" DataTextField="Description" SelectedValue='<%# Bind("TaxId") %>'  CausesValidation="false" MarkFirstMatch="true" AllowCustomText="false" DropDownAutoWidth="Enabled"></telerik:RadComboBox>

[Shinu]

Hi,

You can bind the selected value in edit mode as shown below.
C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
  if(e.Item is GridEditableItem && e.Item.IsInEditMode)
  {
    GridEditableItem item = (GridEditableItem)e.Item;
    RadComboBox combo = (RadComboBox)item.FindControl("RadComboBoxTax");
    combo.SelectedValue = (string)DataBinder.Eval(e.Item.DataItem, "TaxId").ToString();
  }
}

Thanks,
Shinu
