Hello Alexander,

I am just following up  to see if you were able to find user control from row edit template based on details I have provided above.

Feel free to update me if any further assistance needed.

Hello Alexander,

I was able to get user control as well as other controls used in row edit template. I was also able to add controls in user control at runtime also using below lines of code:

TemplateContainer temp = (TemplateContainer)this.WebHierarchicalDataGrid1.GridView.Behaviors.EditingCore.Behaviors.RowEditTemplate.TemplateContainer;
Button btn1 = (Button)temp.FindControl("Button2");
btn1.Text = "chaged";

//Find User Control
UserControl usr = (UserControl)temp.FindControl("Usrt1");

//Add Button to User Control
Button btn2 = new Button();
btn2.ID = "btn1";
btn2.Text = "I ADD1";
btn2.Height = Unit.Pixel(100);
btn2.Width = Unit.Pixel(100);
usr.Controls.Add(btn2);

I have tried below mark up for Row Editing Template:

<ig:EditingCore>
<Behaviors>
<ig:RowEditingTemplate CancelButton="buttonCancel" OKButton="buttonOK">
<Template>
<asp:Button ID="Button2" runat="server" Text="Button" />
<uc1:Usrt ID="Usrt1" runat="server" />
</Template>
</ig:RowEditingTemplate>
</Behaviors>
</ig:EditingCore>

I hope this helps.

Hi, 

Thank you for your answer,

but I don't want to get TemplateContainer, I need to get my own UserControl. 

Actually before I wrote the question here I'd tried a lot of variants, including the suggested one.

So could you please ask development for other variants?

Alexander.

Hello Alexander,

Based on update from development, I understand you may access row edit template on parent grid as shown below: 

TemplateContainer temp = (TemplateContainer)this.WebHierarchicalDataGrid1.GridView.Behaviors.EditingCore.Behaviors.RowEditTemplate.TemplateContainer;

I hope this helps.

Hi,

Thank you!

I am waiting for details on this!

Alexander
