Problem in getting RadComboBox id in Grid Edit command.

[Guruvu]

Hi.

I am getting Object reference not set to an instance of an object error while retriving RadComboBox id in RadGrid edit command.Please help me...

Here is my Code:

 

protected void gvPOW_ItemCommand(object sender, GridCommandEventArgs e)

 

{

 

if (e.CommandName == "Edit")

 

{

 

GridDataItem item = (GridDataItem)e.Item;

 

gvPOW.Rebind();

 

RadComboBox ddlCity = item.FindControl("gvddlPOWCity") as RadComboBox;

 

 

RadComboBox ddlProject = item.FindControl("gvddlPOWProject") as RadComboBox;

 

 

string city = ddlCity.SelectedValue;

 

 

cmd = new SqlCommand("select ProjectName, ProjectId from Projects where CityId =" + ddlCity.SelectedValue, con);

 

 

SqlDataAdapter da = new SqlDataAdapter(cmd);

 

 

DataSet ds = new DataSet("DS");

 

da.Fill(ds,

"Branches");

 

ddlProject.DataSourceID =

null;

 

ddlProject.Items.Clear();

ddlProject.Items.Add(

new RadComboBoxItem("Select Project", "0"));

 

ddlProject.DataSource = ds;

ddlProject.DataBind();

}

}

I want to bind Project details based on City which was selected in Edit mode.Please help me...

Thanks in advance...

Hello Guruvu,

You can try it in ItemDataBound event like below.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridEditFormItem && e.Item.IsInEditMode)// if EditMode is EditForm or PopUp
       {
           GridEditFormItem editItem = (GridEditFormItem)e.Item;
           RadComboBox ddlCity = editItem.FindControl("gvddlPOWCity") as RadComboBox;
           string city = ddlCity.SelectedValue;
           . . . . . . . .
       }
   }

Thanks,
Princy.

Hi Princy,

Thanks for your quick response.

I am already tried in ItemDataBound Event,

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

   {

       if (e.Item is GridEditFormItem && e.Item.IsInEditMode)// if EditMode is EditForm or PopUp

       {

           GridEditFormItem editItem = (GridEditFormItem)e.Item;

           RadComboBox ddlCity = editItem.FindControl("gvddlPOWCity") as RadComboBox;

           string city = ddlCity.SelectedValue;

           . . . . . . . .

       }

   }

Here,I am getting e.Item.IsInEditMode is always false.I am set the property in MasterTable view as below:

<

 

MasterTableView DataKeyNames="POWId" EditMode="EditForms">

Is there any more modifications need to perform.Please tell me...

Thanks...

Hello guruvu,

Try with the following if statement instead:

if(e.Item is GridEditableItem && e.Item.IsInEditMode)
{
    // your code goes here
}

This should evaluate to true for the edit form.

All the best,
