Hi,

I would like to add a column to this grid view with a check box. I've tried the below code but it only produces a single check box. I have a button 'Create a Order'. Before the user could proceed to the next page it should validate that the user has atleast selected one record from the grid before proceeding. Also, how do I save the checked data in a variable so I could print the results on the next page??

Thanks for your help.

<--form-->

AutoGenerateColumns="true"
AllowPaging="true"
Pagesize="20"
AllowSorting="true"
DataKeyNames="Sku,Product_name,Supplier number"
DataMember="DefaultView"
DataSourceID="AccessDataSource1"
ID="GridView1"
runat="server" />

 
        Include?
       
             
       
       

  
  
  

 
  OnClientClick="return confirm('You must at least select one product to create an order.');"
CommandName="Create" />

It produces one checkbox per row, do you want more? In what way?

In your command event handler call a method to read the user's selections.  If they haven't selected anything throw an error. Otherwise you can add the selected SKUs to a session variable which you can retrieve from the next page.

 

         ArrayList SelectedSKUs = GetSelectedSKUs();
        if (SelectedSKUs.Count > 0)
        {
            Session.Add("UserSelectedSKUs", SelectedSKUs);
        }
        else
        {
            //display an error
        }

private ArrayList GetSelectedSKUs()
    {
        CheckBox RowCheckBox = null;
        ArrayList SelectedSKUs = new ArrayList();
        foreach (GridViewRow Row in GridView1.Rows)
        {
            RowCheckBox = (CheckBox)Row.FindControl("RowCheckBox");
            if (RowCheckBox.Checked)
            {
                SelectedSKUs.Add(GridView1.DataKeys[Row.RowIndex]);

            }

        }

        return SelectedSKUs;
    }

Hi Dean, 

It produces just one check box at the bottom of the grid view. I would like a check box per row in the grid view. Do you have any suggestions on ho I could do this.

Thanks,
Paras

Are you sure this your column defintition?

Because, as you notice, the check box is in the Item template, which means it will show up in every row in the gridview. 

If it is not, it is because:

a) you do not have the checkbox in the ItemTemplate

b) you have two gridviews on the page, the checkbox is in a gridview that is only showing in one row.
