Hide a column in UniGrid

I am trying to hide a column of UniGrid as needed in code:

Using following XML:

<?xml version="1.0" encoding="utf-8" ?>
<grid>
  <columns>
    <column source="##ALL##" externalsourcename="FileName" name="FileName " sort=" FileName " caption="Name" wrap="false" width="25%"  />    
    <column source="FileDescription" externalsourcename="FileDescription" name="FileDescription" sort="FileDescription" caption="Description" wrap="true" width="75%"  />
  </columns>
</grid>

gridFiles.GridName = "~/CMSModules/MyModules/FilesDescr.xml";
gridFiles.NamedColumns["FileDescription"].Visible = false;

Unfortunately I cannot find out why the last row throws and error:

gridFiles.NamedColumns["FileDescription"]' threw an exception of type 'System.Collections.Generic.KeyNotFoundException'
base {System.SystemException}: {"The given key was not present in the dictionary."}

what could be wrong?

Is there a better way to hide some columns which are already set in XML?

Thanks,

Vlado

RE:Hide a column in UniGrid

Hello,

You can set the Visible property directly in your XML definition:

<?xml version="1.0" encoding="utf-8" ?>
<grid>
  <columns>
    <column source="##ALL##" externalsourcename="FileName" name="FileName " sort=" FileName " caption="Name" wrap="false" width="25%"  />    
    <column source="FileDescription" Visible="false" externalsourcename="FileDescription" name="FileDescription" sort="FileDescription" caption="Description" wrap="true" width="75%" />
  </columns>
</grid>

Best regards,
Jan Hermann

Kentico Developer	kentico_ivanat - 8/25/2012 4:40:24 PM RE:Hide a column in UniGrid Hi, in this case you will need to move definition you the UniGrid form the xml file to the code behind as described for example here: advanced uni grid Each column is represented by its control so you can play with visibility.
