Hi everyone,
I have a grid view having two button fields as template field with some others fields. I want to get the two cells values of gridview on click event of one button. My code is as follows -

<asp:gridview id="GridView1" runat="server" autogeneratecolumns="False" xmlns:asp="#unknown">
DataKeyNames="ID" >
        <columns>
            <asp:boundfield headertext="UID" datafield="ID" />
            <asp:boundfield headertext="Complaint ID" datafield="Complaint_ID" />
            <asp:boundfield headertext="Type of solution" datafield="TOS" />
            <asp:boundfield headertext="Present Complaint" datafield="Present_Complaint" />
            <asp:boundfield headertext="Disease Name" datafield="Disease_Name" />
            <asp:boundfield headertext="Previous Test" datafield="Investigation" />
            <asp:boundfield headertext="Geneticals Problems" datafield="Genetical" />
            <asp:boundfield headertext="Exercise" datafield="Exercise" />
            <asp:boundfield headertext="Addiction" datafield="Addiction" />
            
            <asp:templatefield>
            <itemtemplate>
            <asp:button id="btn_view" runat="server" text="View" onclick="btn_view_click" />
            </itemtemplate>
            </asp:templatefield>
            <asp:templatefield>
            <itemtemplate>
            <asp:button id="btn_download" runat="server" text="Download" onclick="btn_download_click" />
            </itemtemplate> 
            </asp:templatefield>
        </columns>
    
    </asp:gridview>

I had tried this on click event of view buttons like this.

protected void btn_view_click(object sender, EventArgs ee)
      {
          GridViewRow grow = GridView1.Rows[0];
          TableCell tc = grow.Cells[2];

      }

Thanks Abhinav,
i had already tried that site but the solution given there is not working correctly. i cannot understand the meaning of 'e'.

aswathy.s.88 10-Jul-10 7:48am

Solution 5

the easy way for you would be for the button write the commandname as select and handle the selected index changed event of gridview and from the selectedrow property you can get the values of the columns you need.

Eg: GridView1.SelectedRow.Cells[2].Text

what is the error?

Shining Legend 10-Jul-10 10:48am

check if the e.CommandArgument has any value or not by debugging.

Shining Legend 10-Jul-10 10:51am

I guess here is the mistake:

values = value.Split('~'); //need to be paranthesis not square brackets.

hi,

u can try these codes.

In html page:

XML

<asp:GridView runat=server ID=GridView6  CellPadding=3 CellSpacing=0 AutoGenerateColumns=false>
  <Columns>
   <asp:TemplateField HeaderText="Column1">
     <ItemTemplate>
     <asp:Button runat=server ID=btn_View OnClick="btn_View_Click"  Text="View" />
     </ItemTemplate>
   </asp:TemplateField>
  <asp:BoundField DataField="Column1" HeaderText="Column1" />
     <asp:BoundField DataField="Column2" HeaderText="Column2" />
     <asp:BoundField DataField="Column3" HeaderText="Column3" />
  </Columns>
  </asp:GridView>

In code Pgae:

C#

protected void btn_View_Click(object sender, EventArgs e)
        {
            int rowIndex = (((sender as Button).NamingContainer) as GridViewRow).RowIndex;
            GridViewRow GridViewRow1 = this.GridView6.Rows[rowIndex];
            //......

        }

Hope help u.

Instead of trying to figure out the row index of the button, just use the CommandArgument property in addition to the GridView event bubbling. Then you can go to your datasource for all you want to know about the record in question.

XML

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowCommand="GridView1_RowCommand">
    <Columns>
        <asp:BoundField HeaderText="name" DataField="name"/>
        <asp:TemplateField>
            <ItemTemplate>
            <asp:Button id="Button1" runat="server" Text="View" CommandName="MyView" CommandArgument='<%#Eval("id") %>'/>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

and in code behind

C#

protected void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e)
{
    String id = e.CommandArgument.ToString();
    if (e.CommandName == "View")
    {
        //process the id
    }
}

Solution 4

go to events tab of gridview double click on rowcommand event it will generate the rowcommand event for gridview. and now for CommandArgument of the button write something like this

CommandArgunment='<%#Eval("Column1") + "~" + Eval("Column2") %>'

now in the rowcommand event
string value = e.CommandArgument.ToString();
str[] values = value.Split['~'];

str[0] and str[1] will contain both of the column1 and column2 values respectively.
