No the images will not displayed. If you have the same directory structure in the web server you can use Server.MapPath("/img") + "filename".

Try to use the full path of the image name like:

http://servername/vdname/images/imagename.jpg

Getting a Value of a Hidden Field in Gridview

Good day

On RowDataBound event i have hidden the Field called ID that will appear after the Check Box like this

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
   {
       e.Row.Cells[1].Visible = false;
   }

Now its time to Delete the Selected Records from a Gridview and i have the Following code on the Delete Button

foreach (GridViewRow row in GridView1.Rows)
          {
              CheckBox chkbx = (CheckBox)row.FindControl("myCheckBox");
              // only add non empty staff names
              if (chkbx != null && chkbx.Checked)
              {
                  List.Add(GridView1.Columns[1]);

                  Userarr.Add(GridView1.Columns[2]);

                  for(int i = 0 ; i < List.Count ; i++)
                  {
                      int Staff_ID  = obj.Get_User_Id(Convert.ToString(Userarr[i]),Convert.ToString(Session["ActiveDatabase"]));

                      obj.Responsibility_Caretaker_Remove(Convert.ToInt32(List[i]), Staff_ID,Convert.ToString(Session["ActiveDatabase"]));
                  }


              }

          }

I know you will complain about Arraylist, lets look at the Solution, i will change later.
Now what am doing here is: I add the Value of the second Field and the third to Different Arraylist and using for loop and calling a method that will call a Sp that will Delete the record based on those two Fields. Now my Problem is that the Field

List.Add(GridView1.Columns[1]);

has been set to false in the Visible Property as you have seen above. And am getting index out of bounds errors. How can i get the value on that hidden Field.

Thanks

You can access the text property for the cell even if it is invisible. I'm not sure why you are grabbing the column object from the grid and expecting to get a value from that. I'm also not sure why you are adding to the List in a foreach and then looping through the entire list every foreach iteration?

I think you might want to try something this instead:

foreach (GridViewRow row in GridView1.Rows)
          {
              CheckBox chkbx = (CheckBox)row.FindControl("myCheckBox");
              // only add non empty staff names
              if (chkbx != null && chkbx.Checked)
              {
                      int Staff_ID  = obj.Get_User_Id(Convert.ToString(row.Cells[2].Text),Convert.ToString(Session["ActiveDatabase"]));

                      obj.Responsibility_Caretaker_Remove(Convert.ToInt32(row.Cells[1].Text), Staff_ID,Convert.ToString(Session["ActiveDatabase"]));
              }

          }

Hope this helps.

Hi,
1. At what point are you getting the IndexOutOfRangeException? Have you stepped through your code?

2. Instead of hiding the ID column you can decide not to bind the ID column to the gridview in the first place, by not specifying it in the gridview boundfield collections.

You can set the ID column of the datasource as a Primary Key to the GridView Rows which you can use for your delete.

hope this helps,

Ibrahim

The easiest way is go for a GridView control in asp.net 2.0. You can display the dataset content in a tabular format by writing few lines of code.

It will also maintain the ViewState between postback.

You can also provide the sorting, paging and filter options.

So, finally, i am using GridView control, but one little question more:

How do i set column name as per query column; i.e. suppose select query is :
select Cname as "Candidate Name" from table1. So i wish to give the column name "Candidate Name" like wise.

Thanks & Regards

You can use RowDataBound event. Google it. you can do it like in that event,

"If e.Row.RowType = DataControlRowType.Header Then

do somthing

End If"

You can't use a HTML table in the code-behind to bind it to the dataset. You need to set runat="server" attribute to true. You can also use the HTMLTextWrite class to generate the table. Otherwise, you can always use the grid view control with out writing so many lines of code. But it totally depends on the requirement.
