Hello there guys,

another day, another problem: I just want to add a empty row everytime an user clicks on a button.

My approach: I add it client-side and on the initialize event I fill the dropdown, I have.

I needed to add a dummy-behavior to make it working:

                <Behaviors>
                    <ig:EditingCore>
                        <Behaviors>
                            <ig:RowAdding>
                                <AddNewRowClientEvents />
                                <EditModeActions EnableF2="false" />
                            </ig:RowAdding>
                        </Behaviors>
                    </ig:EditingCore>
                </Behaviors>

The button is just like:

                            <stgwc:ImageLinkButton runat="server" ID="btnCreateNewAttribute" ImageUrl="~/Images/base/Icons/16x16/add2.png"
                                ToolTip="Add new Attribute" OnClientClick="addEmptyRow(); return false;"  />

note: the return false is not tested, but doesnt matter anyway.

Now the BLOCKED SCRIPT

        function addEmptyRow() {
            var grid = $find("<%=dgrIndRoleAttributes.ClientID%>"); // get a reference to the grid
            var values = new Array(grid.get_columns().get_length()); // create a new empty row
            grid.get_rows().add(values) // add the new row
        }

And the initialize in c#:

        private void dgrIndRoleAttributes_InitializeRow(object sender, RowEventArgs e)
        {
            long indRoleAttribId = Convert.ToInt64(e.Row.Items.FindItemByKey("bdIndRoleAttributeId").Value);

            Control control = e.Row.Items.FindItemByKey(COL_INDROLEATTRIUBDESC).FindControl("ddlIndRoleAttribDescr");
            FillIndRoleAttribDropDown(control as DropDown, indRoleAttribId);

            control = e.Row.Items.FindItemByKey(COL_INDROLEATTRIBVAL).FindControl("txtIndRoleAttribValue");
            (control as TextEdit).Text = MapIndRoleAttribValue(indRoleAttribId);

            control = e.Row.Items.FindItemByKey(COL_INDROLEATTRIBACTION).FindControl("btnDeleteAttribute");
            JScriptHelper.RegisterConfirmBeforeDelete(control as ImageLinkButton);
        }

Does not matter, just some business logic.

Well, on the first klick it works fine, but then it just overrides the new row, no matter how many times I click.

Is there a reason to do this? Does the Add_row not check the rows but the datasource, where (I guess so?) the new entry isnt added?

Thanks for your response and have a nice weekend
