[Solved] Implementing custom GridTextColumnEditor

[Ignas]

I'm not sure I quite understand how the extension of GridTextColumnEditor goes, say I have extended the class like this:

public class CustomEditor : GridTextColumnEditor

{

private TextBox textBox;

protected override void LoadControlsFromContainer()

{

this.textBox = this.ContainerControl.Controls[0] as TextBox;

}

public override bool IsInitialized

{

get

{

return this.textBox != null;

}

}

public override string Text

{

get

{

return "salmon";

}

set

{

this.textBox.Text = value;

}

}

protected override void AddControlsToContainer()

{

this.textBox = new TextBox();

this.ContainerControl.Controls.Add(this.textBox);

}

}

But the field still gets updated with the value entered in the textBox, instead of "salmon". Why is this? I want to implement a custom editor which consists of two TextBoxes, which contain the cell value splitted by the first whitespace character, and it returns the the value combined from the two TextBoxes.

Hi Ignas,

How do you attach your column editor to your column? Here is an example using RadGrid's CreateColumnEditor event:

void RadGrid1_CreateColumnEditor(object sender, GridCreateColumnEditorEventArgs e)
{
    if (e.Column is GridBoundColumn && (e.Column as GridBoundColumn).DataField == "PriceOnDate")
    {
        e.ColumnEditor = new CustomEditor();
    }
}

Also, in your overridden AddControlsToContainer() method you need to set an ID for your server text box. Otherwise you will get a "ViewState failed to load" exception on your page.
