[Solved] Extracting values from editable grid template column

[Elena]

I have a simple grid with template column:

<

 

telerik:GridTemplateColumn HeaderText="Notification" UniqueName="TemplateColumn"

 

 

 

EditFormColumnIndex="1" ReadOnly="false">

 

 

 

<ItemTemplate>

 

 

<%

# Eval("vchNewsText") %>

 

 

 

</ItemTemplate>

 

 

 

 

<EditItemTemplate>

 

 

 

<span><telerik:RadTextBox runat="server" ID="txtNotification" Width="750px" height="200px"

 

 

 

TextMode="MultiLine"

 

 

 

Text='<%# Bind("vchNewsText") %>'></telerik:RadTextBox><span></span>

 

 

 

</EditItemTemplate>

 

 

 

</telerik:GridTemplateColumn>

 

</Columns>

 

 

 

User is supposed to add a new row and fill in the vchNewsText field.

In Grid_ItemCommand procedure I am  trying to extract new value from txtNotification TextBox in order to update
dataset. 

s1 = (editedItem.FindControl(

"txtNotification") as TextBox).Text;

 

 

Result-control not found 

Another try was:

 

Hashtable newValues = new Hashtable();

 

e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);
s1=(string)newValues["TemplateColumn"];

Result-empty string;

So how do I extract the new value of Control in Template Column in Grid_ItemCommand procedure ?

Hello Elena,

I suppose you want to access the textbox after the user has entered some text inorder to add a new row to the grid. If thats the case then you would have to access the insert item and not the edit item.
If you are using 'InPlace' EditMode then try out the following code:
c#:

  protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "InsertCommand")
        {
            GridDataInsertItem insertItem = (GridDataInsertItem)e.Item;
            string s1 = (insertItem.FindControl("txtNotification") as TextBox).Text;

        }
    }

or else if you are using 'EditForms' EditMode then try out the following code:
c#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
       if (e.CommandName == "InsertCommand")
        {
            GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item;
            string s1 = (insertItem.FindControl("txtNotification") as TextBox).Text;

        }
    }

Thanks

Princy,It did not help. s1 string comes empty.
And e.Item.ItemType ahows like EditItem.

Here is proc text:

 

if

 

(e.CommandName == "PerformInsert")

 

{

 

 

DataTable dsAlertTable = (DataTable)Session["dsAlertTable"];

 

 

DataRow newRow = dsAlertTable.NewRow();

 

 

 

 

// s1 = (editedItem.FindControl("txtNotification") as TextBox).Text;

 

 

 

 

 

 

GridDataInsertItem insertItem = (GridDataInsertItem)e.Item;

 

 

 

string s1 = (insertItem.FindControl("txtNotification") as RadTextBox).Text;

 

 

;

 

 

 

 

 newRow["vchNewsText"] = s1;

 

 

 

 

 

newRow[

"dtStart"] = DateTime.Today;

 

 

newRow[

"dtInsertDate"] = DateTime.Today;

 

dsAlertTable.Rows.Add(newRow);

 

// rgIDCAlert.DataSource = dsAlertTable;

 

 

 

 

 

 

rgIDCAlert.MasterTableView.IsItemInserted =

false;

 

 

// rgIDCAlert.Rebind();

 

 

 

 

 

 

return;

 

}


And I use "Add New"  CommandItem to add empty row to grid;But I can't retrieve the input.
