[Solved] error to display image in Grid

[Truong Pham]

I have tried to display image on Grid using GridBinaryImageColumn but when run it display error:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Parameter is not valid

I include here the my source code:

 

<

 

telerik:GridBinaryImageColumn DataField="CUST_LOGO" HeaderText="Image" UniqueName="Upload" ImageAlign="NotSet"

 

 

 

 

 

ImageHeight="80px" ImageWidth="80px" ResizeMode="Fit" DataAlternateTextField="CUST_NAME"

 

 

 

 

 

DataAlternateTextFormatString="Image of {0}">

 

 

 

 

 

<HeaderStyle Width="10%" />

 

 

 

 

 

</telerik:GridBinaryImageColumn>

 

In  my database the "CUST_LOGO" field sometime contain NULL value.

That error should be thrown when the data that you are giving the GridBinaryImageColumn is not a valid image or has custom headers applied. Does this error display each time you run your app? Have you tried to run it without any of the nulls that you mentioned? There could be an issue where the nulls are causing the problem.

This is probably caused by the DataAlternateTextField which only works some of the time and kicks up that error following rebinds. Try removing that property from the column def.
