Adding a row to the telerik radgrid from a button which is outside the rad grid

[Deepika]

Hello,

This is my requirement --

1. I do not want to have the Add New Record button in Grid.
[ I have handled this as below in ItemDataBound event --]

if

(e.Item is GridCommandItem)  

{ 

//Hide Addnew and refersh button from code behind  

 

GridCommandItem cmditem = e.Item as GridCommandItem;  

if (cmditem.FindControl("InitInsertButton") != null)

 {

cmditem.FindControl("InitInsertButton").Parent.Visible = false; 
}

}

2. I have a button "Add New Record" outside the grid, Onclick of this, I want to insert a row in Grid.
Additional Information --
1. I ahve the below piece of code in my aspx page -

<telerik:GridEditCommandColumn UniqueName="EditColumn" ButtonType="ImageButton" HeaderText="Edit"> 

<ItemStyle Width="10%" HorizontalAlign="Center" />
<HeaderStyle Width="10%" HorizontalAlign="Center" /> 

<FooterStyle Width="10%" HorizontalAlign="Center" />
</telerik:GridEditCommandColumn>

2. When I tried the below piece of code on buttn click,

GridName.MasterTableView.ShowFooter = true;
GridName.Rebind(); 
 

I am not getting the Edit image button.

Please suggest.

Hello,

Try the following to insert new record on external button click.
CS:

protected void btn_Click(object sender, EventArgs e)
  {
      GridCommandItem commandItem = (GridCommandItem)RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem)[0];
      commandItem.FireCommandEvent("InitInsert", null);
  }

Thanks,
Princy.

Hello Princy,

Thanks for your suggestion. But I have another problem, I have a Checkbox column in the aspx page. That I set or Reset  based on a Database returned value.

Because this is a new row, I do not have nything in DB and the Edit Item template is getting  triggered and is causing problem. bec I have below line of code --

Checked

 

 

='<%# Convert.ToBoolean(DataBinder.Eval(Container.DataItem, "ActiveStatus")) %>'

I have this error in my log --
[Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.]

Any suggestions?
Thanks Again ..

Hello Deepika,

 The error suggests that the problematic line of code is trying to be execute outside of a databound control. Do you have the checkbox inside the RadGrid or in any other databound control? Can you post a sample of the markup? Additionally you can also add a check so that the Eval method is only executed in case the item is in EditMode. 

(Container is GridEditFormInsertItem) ? false :
Convert.ToBoolean(DataBinder.Eval(Container.DataItem, "ActiveStatus")) %>'

Kind regards,
Marin
