{

if (e.Item.OwnerTableView.Name == "Detail2" && CommandState == "editselected")

TextBox txtBox = (TextBox)item["Sortorder"].FindControl("tbVisitSortOrder");

txtBox.Visible = true;

}

Please help, any response would really be appreciated.

Thanks!

Hello Lyzel,

You need to get reference to corresponding DetailTable row (check for the TableView Name) and then use the FindControl() method to access the control placed inside that. Here is the code for described scenario.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode && e.Item.OwnerTableView.Name == "Detail2")

{

GridEditableItem editItem = (GridEditableItem)e.Item;

TextBox txt = (TextBox)editItem.FindControl("tbVisitSortOrder");

// txt.Visible = true;

}

Thanks,
Princy.

Thanks Princy!

I have another problem, the "detail2" detail table allow to edit multiple rows.

How can i check if row is selected for edit?
How to get the data key value of selected row?

Below is my code.

if (e.CommandName == "Update")

{
GridCommandItem cmditem = (GridCommandItem)e.Item;
GridTableView tableView = (GridTableView)cmditem.NamingContainer.Parent;

foreach (GridDataItem item in tableView.Items)

{

int cpid = Convert.ToInt32(item.SavedOldValues["cp_id"]);

TextBox txtVisitFreq = (TextBox)item.FindControl("tbVisit");

TextBox txtVisitSortOrder = (TextBox)item.FindControl("tbVisitSortOrder");

UpdateVisitFreq(cpid, txtVisitFreq.Text, Convert.ToInt32(txtVisitSortOrder.Text));

item.Edit = false;

tableView.Rebind();

}

Regards,
Lyzel

Hello Lyzel,

You can try the following method to get the value of edited row.

C#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == "Update")

{

if (e.Item.OwnerTableView.Name == "Detail2")

{

GridTableView table = (GridTableView)e.Item.OwnerTableView;

foreach( GridEditableItem editItem in table.GetItems(GridItemType.EditItem) )// loops through all edited rows

{

string dataKeyValue = item.GetDataKeyValue("cp_id").ToString(); // getting DataKeyValue of edited rows

// your code

}

Thanks,
Princy.
