Hi Sameer,

I have checked the sample. You have canceled DockVisibilityChanging event of docked control. This is the cause of the issue.

Herewith I have attached the modified sample. Please have a look at this and let me know if it meets your requirements.

Thanks for choosing Syncfusion products.

Hi,

commenting arg.Cancel=true statement does not meet my requirement as It was used to close only one tab. After commenting this if you click on x all tabs gets closed. And this is the sample provided in one of syncfusion forum to close only single tab. If you have any other work around please send me.

Thanks
Sameer

Hi Sameer,

Please modify your Load button click event handler code snippet as follows

private void button2_Click(object sender, System.EventArgs e)
{
flag=false;
SetDockingState( this.xmlDockString );
}

and let me know if it helps.

Thanks,

Hi Murugan,

I saw your vedio file. You are missing steps I have told you that It happends with tabbed floating not just simple one control float.
Here are steps again for your reference
- Tab two controls.
- Float by dragging it outside form
- close one control on clicking X
- Save dock state
- Load doc state then it give Invalid Controller message

Thanks

Hi Sameer,

Sorry the mistake in reproducing steps. Herewith I have attached the video. I have checked the issue with the given reproducing steps. We could not reproduce the issue here. Could you please provide me the video that shows the issue? I could see some hard behavior in v4.4. Are you upgraded to v4.4? Please let me know your Esential Studio version details if any upgrades.
