GridView EditItemTemplate DropDownList Problem

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :ASP.Net
 

I'm creating a GridView that displays the details of an order.  One of the columns shows which Location the order went to.  All the information is correctly displayed and is based on a single SQL query (SqlDataSource1). 

When they edit the item, I have another SQL query (SqlDataSource2)  that correctly pulls a list of all the customer's locations and populates a DropDownList.  The issue I'm having is trying to set the SelectedValue of the DropDownList to the Location value, which is pulled in the first SQL query.

Here's what I've been working with so far... 

<asp:TemplateField>

Weird problem in Detailsview - Dropdownlist in

  

Hi,

I'm new in this forum and I really hope you'll be able to help me.

I converted a field in the detailsview into a template field and put a dropdownlist in the <InsertItemTemplate> and it worked great. This is the code I put:

<InsertItemTemplate><asp:DropDownList runat="server" DataSourceID="sdsGenresPossible" DataTextField="Genre"  DataValueField="Index" SelectedValue='<%# Bind("Genre") %>' ></asp:DropDownList></InsertItemTemplate>


Now, I tried to do the same thing for the <EditItemTemplate> . This is the code I put there:

<EditItemTemplate><asp:DropDownList runat="server" DataSourceID="sdsGenresPossible" DataTextField="Genre" DataValueField="Index" SelectedValue='<%# Bind("Genre") %>' ></asp:DropDownList></EditItemTemplate>  

When I change the DV properties I do see that a dropdownlist was  added but when I run the program and click on "Edit" in the DV nothing happens (however when I click on "Insert" it works fine).

This is the Select command for the data source I used:

<asp:SqlDataSource runat="server"
          

Problem Binding DropdownList in a gridView to a datasource

  
I have a Dropdownlist in an itemTemplate in a gridview. My gridView binds to dataTable1 (from which the selected value for dropdown comes from) and dropDown binds to dataTable2 (i need to get DataValueField and DataTextField from here).<asp:TemplateField HeaderText="Category"> <ItemTemplate> <asp:DropDownList ID="Cat" runat="server" SelectedValue='<%#Bind("CATEGORY") %>' > </asp:DropDownList> </ItemTemplate> <FooterStyle BorderStyle="None" /> <HeaderStyle BorderStyle="None" /> <ItemStyle BorderStyle="None" /> </asp:TemplateField>How do I do that? thanks in advance!

Gridview Dropdownlist databinding problem

  

I am using gridview, in ItemTemplate  I am using dropdownlist which has the hard-coded value, I want to get updated value of dropdownlist from database, but whenever I use EVAL, it throws the following error:


 'ddl' has a SelectedValue which is invalid because it does not exist in the list of items.

Parameter name: value


I am using the following code:

<asp:TemplateField HeaderText="Status"  >
                  <ItemTemplate>
                      <asp:DropDownList ID="ddl" runat="server" SelectedValue='<%# Bind("Status")%>' >
      

Problem to group radio button across gridview rows

  
In general no one can easily group or make a single selection from radio button list inside gridview rows. There are a lot of way to make a single or unique selection from list. Here i want to share how i can address this problem in the most easiest way. Googling the problem most of the cases i saw the grouping in horizontal way. Thats why i tried to group the radio buttons in vertical manner. Let i have a requirement like below:

How to bind GridView and DropDownList controls using DataTable object

  
In .net framework 2.0, you can load a DataTable in memory by consuming a data source using a DataReader. In this version you will find the flexibility in accessing the DataReader means write access code once and use again and again using DataReader. To see the functionality of DataTable consider an example that is created using VS2005.

Gridview Enable Selection Problem

  

Hi,


I have a gridview with Enable selection and Enable Paging equals to TRUE.

I also set the PageSize of my gridview to 4 so that I only displays 4 rows per page.

The problem is when I click the pager in the bottom of my gridview, my gridview is disappearing and no records appear.


Here is code behind of my gridview:

If e.Row.RowType = DataControlRowType.DataRow Then
                e.Row.Attributes("style") = "cursor:pointer"

                e.Row.Cells(2).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(3).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(4).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(5).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(6).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))

Excel-like experience - gridview focus problem

  

Hi.

I'm creating a page where people can order several items from a list without having to press "edit" and "save" in between like you normally would in a gridview. The user writes down the quantity, and finally presses a "submit" button that saves the order.

I want the user to have a windows form (or excel) like eperience, so once the user puts in the quantity and moves on to the next item, either by TAB or by clicking on the TextBox, i make some calculations without the user beeing bothered with a full refresh or having to press a buton to execute the event, so I place the controls inside an UpdatePanel and use TextBox.TextChanged. The event runs code that calculates the sum for the row (price * quantity) and shows that in a column called "Sum", and updates a label in a fixed position with the new order total ("Total").

Any ideas on how to achieve this?

Right now I use a GridView with a templatefield for the Quantity and set the TextBox.TextChanged event to fire to make the calculations. The problem is that the focus then changes.


By using SmartNavigation or the ScriptManager.SetFocus I manage to retain focus on the TextBox that executed the Postback, but the user might have moved on to a textbox far down the gridview (thus causing the postback by leaving the previo

GridView Problem

  

I've been asked to change an ASP.NET project to MVP Architecture - which may have something to do with what is going wrong.

I make the call through the architecture to the database which returns a dataset which I've verified is correct, (using dataset.writeXML() ) just before databinding  to the gridview.

On one page everything works as expected (plus any post backs). Another page the Page_Load works correct and the gridview is populated, but any postbacks do not work- it retains the Page_Load's data. Then on the third page the GridView never shows though databinded. In all these cases I've checked that the Dataset is good data, and made sure to DataBind().

All three use the exact same logic. Any ideas or suggestions are greatly appreicated.

Thank you for your help.

Problem with "Edit" and "Delete" buttons in gridview!

  
Hi everyone. I have problem with the buttons Edit and Delete in Gridview for very long time and i really need help about it. So i have gridview and sqldatasource. First i try to make this buttons manually and as you will see in sqldatasource 5 and 6 i have these buttons my records show up but the buttons not working. After that i was advised to do it automatically with gridview smart tag options and Generate columns - this is what i did in sqldatasource7 and gridview7. But both ways i need to change the statements with my own because that what they create not works. So select statement works. Now the error that i get in both ways is the same:The GridView 'GridView(the number could be 5,6 or 7)' fired event RowEditing which wasn't handled.See how looks my page:Now here's my code in aspx:<%@ Page Language="C#" Title="Specific Search in Phone Directory" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %> <html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="serv
