Detailsview always editing first row of the gridview, On DynamidData custom pages.

Question

User-1759624489 posted

 Hello. When I click the button edit on the gridview

 

protected void OnGridViewRowEditing(object sender, EventArgs e) {
        //DetailsView1.ChangeMode(DetailsViewMode.ReadOnly);
        GridView1.EditIndex = -1;
       
        DetailsView1.ChangeMode(DetailsViewMode.Edit);
    }

 

The detailsview is set in edit mode, but not on the selected row but on the first row always.

 

Any idea??

    <asp:LinqDataSource ID="GridDataSource" runat="server" EnableDelete="true" EnableUpdate="true">
           <WhereParameters>
                    <asp:DynamicControlParameter ControlID="FilterRepeater" />
                </WhereParameters>
            </asp:LinqDataSource>

            <asp:Panel ID="DetailsPanel" runat="server">
              <br /><br />

              <asp:LinqDataSource ID="DetailsDataSource" runat="server" EnableDelete="true" EnableInsert="true" EnableUpdate="true">
                  <WhereParameters>
                      <asp:DynamicControlParameter ControlID="GridView1" />
                  </WhereParameters>
              </asp:LinqDataSource>

 I have tried everything.

 

  <asp:LinqDataSource ID="DetailsDataSource" runat="server" EnableDelete="true" EnableInsert="true" EnableUpdate="true" Where="Id==@Id">
                  <WhereParameters>
                          <asp:ControlParameter ControlID="GridView1" PropertyName="SelectedDataKey" Name="Id" />  
                  </WhereParameters>
              </asp:LinqDataSource>

 

It gave me this error:

Operator '==' incompatible with operand types 'Int32' and 'Object'

 Try to add DefaultValue to ControlParameter,because its probably returning Null.

Also try

<WhereParameters>

<asp:ControlParameter ControlID="GridView1" Name="Id"

PropertyName="SelectedValue" Type="Int32" />

</WhereParameters>
