Hello Niloofar,

Following is a sample code to achieve your requirement.

Usercontrol(ASCX):

<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>

<br />

<telerik:RadTreeView ID="RadTreeView1" runat="server" AllowNodeEditing="True">

<Nodes>

<telerik:RadTreeNode Expanded="true">

<Nodes>

</Nodes>

</telerik:RadTreeNode>

</Nodes>

</telerik:RadTreeView>

ASPX:

<telerik:RadGrid ID="RadGridAddress" runat="server" >

<MasterTableView CommandItemDisplay="Top" DataKeyNames="EmployeeID">

<Columns>

<telerik:GridEditCommandColumn UniqueName="EditCommandColumn">

</telerik:GridEditCommandColumn>

</Columns>

<EditFormSettings UserControlName="~/RadGrid/UserControl_EDIT.ascx" EditFormType="WebUserControl">

<EditColumn UniqueName="EditCommandColumn1">

</EditColumn>

</EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

C#:

int rowindex = -1;

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == RadGrid.EditCommandName)

{

GridDataItem item = (GridDataItem)e.Item;

rowindex = item.ItemIndex;

}

protected void RadGridAddress_PreRender(object sender, EventArgs e)

{

if (rowindex > -1)

{

GridEditFormItem editItem = (GridEditFormItem)RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem)[rowindex]; // accessing edit form

GridDataItem item = (GridDataItem)editItem.ParentItem;

UserControl userControl = (UserControl)editItem.FindControl(GridEditFormItem.EditFormUserControlID); //accessing user control

TextBox txtbox = (TextBox)userControl.FindControl("TextBox2"); //accessing textbox in user control

RadTreeView treeview = (RadTreeView)userControl.FindControl("RadTreeView1");//accessing treeview in user control

RadTreeNode node = (RadTreeNode)treeview.Nodes[0];

txtbox.Text = item.GetDataKeyValue("EmployeeID").ToString(); // setting DataKeyValue to TextBox

node.Text = item.GetDataKeyValue("EmployeeID").ToString();// setting DataKeyValue to TreeView node

rowindex = -1;

}

Thanks,
Princy.

Hello Niloofar,

You can try the following conditon to check whether the grid is in insert mode.

C#:

protected void RadGridAddress_PreRender(object sender, EventArgs e)

{

if (RadGridAddress.MasterTableView.IsItemInserted)

{

GridEditFormInsertItem editItem = (GridEditFormInsertItem)RadGridAddress.MasterTableView.GetInsertItem();

UserControl userControl = (UserControl)editItem.FindControl(GridEditFormItem.EditFormUserControlID);

TextBox txtbox = (TextBox)userControl.FindControl("TextBox2");

RadTreeView treeview = (RadTreeView)userControl.FindControl("RadTreeView1");

. . . . . . . .

}

Thanks,
Princy,

Hello Niloofar,

Make the following modification in the above code and see if it works now.

ASPX:

<telerik:RadGrid ID="RadGridAddress" runat="server" OnItemDataBound="RadGridAddress_ItemDataBound" DataSourceID="SqlDataSource1" >

<MasterTableView CommandItemDisplay="Top" DataKeyNames="EmployeeID">

<Columns>

. . . . . .

</Columns>

<EditFormSettings UserControlName="~/RadGrid/UserControl_EDIT.ascx" EditFormType="WebUserControl">

<EditColumn UniqueName="EditCommandColumn1">

</EditColumn>

</EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

ASCX(UserControl):

<asp:TextBox ID="TextBox1" runat="server" Text="xx"></asp:TextBox>

<br />

<telerik:RadTreeView ID="RadTreeView1" runat="server" AllowNodeEditing="True">

<Nodes>

<telerik:RadTreeNode Expanded="true">

<Nodes>

</Nodes>

</telerik:RadTreeNode>

</Nodes>

</telerik:RadTreeView

<asp:Button ID="Button1"

Text='<%# (Container is GridEditFormInsertItem) ? "Insert" : "Update" %>'

runat="server" CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>'></asp:Button

<asp:Button ID="btnCancel" Text="Cancel" runat="server" CausesValidation="False"

CommandName="Cancel"></asp:Button>

C#:

protected void RadGridAddress_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditFormItem && e.Item.IsInEditMode && !e.Item.OwnerTableView.IsItemInserted)

{

GridEditFormItem editItem = (GridEditFormItem)e.Item;

GridDataItem item = (GridDataItem)editItem.ParentItem;

UserControl userControl = (UserControl)editItem.FindControl(GridEditFormItem.EditFormUserControlID);

TextBox txtbox = (TextBox)userControl.FindControl("TextBox1");

RadTreeView treeview = (RadTreeView)userControl.FindControl("RadTreeView1");

RadTreeNode node = (RadTreeNode)treeview.Nodes[0];

txtbox.Text = item.GetDataKeyValue("EmployeeID").ToString();

node.Text = item.GetDataKeyValue("EmployeeID").ToString();

}

if (e.Item is GridEditFormInsertItem && e.Item.OwnerTableView.IsItemInserted)

{

GridEditFormInsertItem editItem = (GridEditFormInsertItem)e.Item;

UserControl userControl = (UserControl)editItem.FindControl(GridEditFormItem.EditFormUserControlID);

TextBox txtbox = (TextBox)userControl.FindControl("TextBox1");

RadTreeView treeview = (RadTreeView)userControl.FindControl("RadTreeView1");

RadTreeNode node = (RadTreeNode)treeview.Nodes[0];

txtbox.Text = "some text";

node.Text = "some text";

}

Thanks,
Princy.

Hi,

Can anyone please help me with adding existing records of a radgrid. I have a radgrid with parts and quantities. I put in a column with add option that comes up on all records as shown below. I want the syntax for a situation where up on the add button click on each record; I want to fill the Part Num and Quanitity field of the web user control to be auto filled by grabbing the values from the Part Num and Quantity fields of that record. Please see the picture below for understanding.

Thank you,

Kiran.
