Hello experts,

I have a gridview with a checkbox column.  I am binding the gridview to a dataset. The first column in the dataset is bool (true\false).  When the page loads, how can I programmatically check the check boxes if the dataset column == true?

Thanks in advance.

            <asp:GridView ID="gvPayments" runat="server" AutoGenerateColumns="false"
                DataKeyNames="rowid" GridLines="None" AllowPaging="false" CssClass="gvGrid"
                PagerStyle-CssClass="pgr" AlternatingRowStyle-CssClass="alt"
                >
            <Columns>    
                <asp:TemplateField>
                    <HeaderTemplate>
                        <asp:CheckBox ID="ChkAll" runat="server" />
                    </HeaderTemplate>
                    <ItemTemplate>
                        <asp:CheckBox ID="chkSel" class="chkSel" runat="server" />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:BoundField DataField="path" HeaderText="path"
                    SortExpression="path" />
                <asp:BoundField DataField="valuetext" HeaderText="value"
                    SortExpression="valuetext" />
            </Columns>
            </asp:GridView>

This could be done in the RowDataBound event.

You could first add the boolean column to the DataKeyNames.
DataKeyNames="rowid, boolCol"
 protected void gvPayments_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                CheckBox chkBox = (CheckBox)e.Row.FindControl("ChkAll");
                bool col1 = (bool)GridView1.DataKeys[1].Value;
                chkBox.Checked = col1;
            }
        }

Open in new window


Or you could bind it in the GridView markup.

<asp:CheckBox ID="ChkAll" runat="server" Checked='<%# Bind("boolColID") %>' />
