Asp.Net show gridview header when there is no data or empty

Recently I have facing gridview header display issues when DataSource is empty or null.

So for same i have googing and find the solution like how to show header even DataSource is empty or null.

Before I was written the blog post, think it like it's a chunk of code but might be useful to someone who facing the same issue.

Generally, writing the condition to check any DataTable, DataSet, List or any collection have data then we assign to that collection/DataTable to GridView DataSource.

So let's see example. How to create and assign dummy table to DataSource then display the header without any data record.

if (dt.rows.count > 0)
{ 
    grdview.DataSource = dt;
    grdview.DataBind();
}
else
{

    var dummyTable = new DataTable();
     dummyTable.Columns.Add("Column1");
        dummyTable.Columns.Add("Column2");
        dummyTable.Rows.Add(dummyTable.NewRow());
        grdview.DataSource = dummyTable;
        grdview.DataBind();
        grdview.Rows[0].Style.Add(HtmlTextWriterStyle.Display, "none");
}

Hope you would like it and please share your suggestions and comments for improvement.

Use .VB and .CS class file in one website using asp.net

When I was creating my one of the site, I chose to write it in C#. I had a problem with the App_Code folder because I had some code in VB.NET code and some C# code I needed to put in there. I didn't want to rewrite my VB.NET code in the App_Code folder just so I could write the rest of the code for the site in C#.

Luckily, the ASP.NET Team had already thought about just this kind of circumstance. They implemented a way to partition the App_Code folder into sub-folders, one for each set of code files written in the same programming language. Awesome, I didn't have to spend a couple hours converting code from VB.NET to C#!

The below works with ASP.NET 2.0 and later.

Even if you don't use multiple different programming languages for your code files in the App_Code folder, you could use this feature to organize your sets of related code files into sub-folders.

Step 1: Add the following lines to the web.config

<configuration>
<system.web>
<compilation>
<codeSubDirectories>
<add directoryName="VB_Code"/>
<add directoryName="CS_Code"/>
codeSubDirectories>
compilation>
system.web>
configuration>

Step 2: Create a sub-folder in the App_Code folder for each language you want to support.
For Example:
/App_Code/VB_Code
/App_Code/CS_Code

Step 3: Place your VB.NET code in the VB_Code folder and place C# code in the CS_Code folder.
