When i go to my detailsview itemtemplate, the checkbox returns the value correct, but every time i update it, it always returns 0.I'm using a MySQL db and the type of "grabbelpas" is tinyint(1).If more code is needed just ask. But my other textboxes are updated correctly, it's just the checkbox that doesnt update well.
I have a gridview and a detailsview, the detailsview has a checkbox in it, I need to get the value of the checkbox when the user updates that record.
If the value is true then insert todaysdate.
The problem is that I cannot get it the value back.
Some code:
[Code]....
Here's part of my markup
<asp:TemplateField HeaderText="Approval" Visible="false">
<InsertItemTemplate>
<asp:CheckBox ID="Approved" runat="server"/>This must be checked to allow the insert.
</InsertItemTemplate>
Here's my code

I am trying to arrange the information from a SQL record into a 3 column by 3 row table to fit the form presentation that I want. I have placed on the page 3X3 table and then tried to place a detailsview in the first cell for the first picture called P1dv.
I have place a detailsview in the last cell that would control the paging of information called Controldv. I need to fiqure out how to link P1dv paging to Controldv page action. I am using visual web dev. 2005. I am not updating or editing these are read only views.
example of what i need the form output to look like:
picture1 picture2 picture3
name1 name2 name3
Contact1 contact2 contact3

I´m trying to link the gridview to detailsview and I used this page as my inspiration:
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.
.aspx
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AllowPaging="True" PageSize="10" OnPageIndexChanging="countryGrid_PageIndexChanging"
CellPadding="4" ForeColor="#333333" Width="400px" Font-Size="9pt" [code].....
I've been working for a long time with GridViews and DetailsViews, but yesterday I've come across a new scenario, which I quite do not understand.
I have a GridView with ImageButton (CommandName="Insert") which will change the mode of the DetailsView to Insert. Afterwards I'll look for a DropDownList inside that DetailsView and add some items dynamically. Works fine, but one first the first time I press that ImageButton. If I click on "Cancel" in the DetailsView and press the ImageButton again, the .FindControl() Method returns null.
I've created this sample: (To make it run in your Visual Studio, just bind a DataSource to the DetailsView, otherwise it will not be rendered)
Markup:
<asp:GridView ID="gvCategory" runat="server" OnRowCommand="gvCategory_RowCommand">
<Columns>
</Columns>
<EmptyDataTemplate>
[Code]....
I have also tried using a ItemTemplate, and not a InsertItemTemplate, but this results in the same. After using the ChangeMode-Method the DetailsView.CurrentMode == InsertMode. The only thing I can think of is, that the markup is already generated for the ItemTemplate and changing the Mode to InsertMode can't affect the rendered markup, or something like this.
I want to select all checkBox in Gridview when click to header checkBox.I have created design such that CheckBox is not available to header of Gridview.It is in other table. Below is design of gridview.

when i click chk_packages checkbox myCheckedChanged fired and i want single checkbox to get enable
I am displaying my table data using listview control. It is working fine.
Now I would like to add a checkbox in front of every item so then when user checks the checkbox and click on delete button inside or outside the listview control then i want all the records to be deleted.
How can i see if a check box was checked with razor. I am trying to do Request["checkbox"] and it returns nothing. (checkbox is the "name" of the checkbox).
View 5 RepliesI have created a single checkbox in the DetailsView of my Asp page. I then created VB code behind to set the value =1 if the checkbox is checked and value =0 if checkbox is not checked. I cannot get the code to work. The record will get created in my SQL database, but the checkbox field remains NULL
In SQL table, my field and datatype is: Greenfield, bit, NULL
The beginning code for DetailsView1 is:
Code:
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" BackColor="White" BorderColor="White" BorderStyle="None" BorderWidth="1px" CellPadding="3" CellSpacing="2" DataKeyNames="ID" DataSourceID="tblEntryFormDS" style="text-align: left; margin-bottom: 0px;" Font-Bold="False" Font-Names="Arial" Font-Size="Small" DefaultMode="Insert" GridLines="Horizontal" CssClass="auto-style47">
<AlternatingRowStyle BorderStyle="None" />
The code for the checkbox within DetailsView1:
Code:
<asp:CheckBox ID="CheckBox1" runat="server" Text=" Greenfield" AutoPostBack="True" />
And the VB code behind. I originally used OnCheckedChanged but that wasnt working and it was suggested of me to use DetailsView1_ItemInserting instead: (The Dropdownlists in the code are working)
Code:
Protected Sub DetailsView1_ItemInserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewInsertEventArgs) Handles DetailsView1.ItemInserting
Dim DropDownList6 As DropDownList = CType(DetailsView1.FindControl("DropDownList6"), DropDownList)
Dim DropDownlist9 As DropDownList = CType(DetailsView1.FindControl("DropDownList9"), DropDownList)

I am using a Gridview binded to a LinqDataSource that represents a database view. The gridview paging is enabled. When navigating from page 1 to page 2, it displays the right count of rows in this page (assume pagesize is 10 and page 2 should have 4 rows only to have total of 14 rows in the view; the datasource), however, it populates wrong data (from the previous page). On the contrary, when I disable paging, everything works ok.

Since I am not using a DataSourceId at the markup I am having to create my own Sorting handler. I found a sample on MSDN but the variable 'dataTable' always returns null why?

I have a listview control on a page. Every item in the ItemTemplate has a LinkButton control with CommandName="Edit". When I click one of these links, the listview goes into edit mode. However, it only goes into edit mode for the first item on the list, because the NewEditIndex is always 0, regardless of which item I click on. I can click on the third item and the NewEditIndex will still be 0, so the first item will go into edit mode. Below is some code.
<asp:ListView ID="lvwQuestion" runat="server" DataKeyNames="qstn_id"
OnItemEditing="lvwQuestion_ItemEditing">

I have in my code a gridview that I redirect to excel, it works fine when I have data in the data set. waht I want is to show column headers when there is no data right now what i get is empty sheet.
View 7 RepliesI am tryting to reach controls in the gridview rows by RowCommand event. I can take values of controls which are binded to gridview source successfully . But for all other controls which is not binded to gridview returns NULL value. All controls run at server. Why is that?
View 7 RepliesI have an aspx page with the following controls:
2 DropDown lists
1 ListView
1 FormView
The procedure is as follows:
STEP 1:
One selects items from the dropdown lists and click the Search button.
The ListView displays all the entries that match the criteria.
STEP 2:
Each entry in the ListView is clickable to select more details in the FormView.
Everything works perfectly well. However I'm testing the selected values after each postback based on the following script:
[Code]....
Now after STEP 1 (Search button) I get the selected ddl values. GREAT so far.
However in STEP 2 and in order to get the selected value of theListView I have to click twice on the same entry in the ListView. The ListView1.SelectedValue is returning 0 after the first click. The correct value is displayed after the second click.
I have a store procedure that loops through items and returns multiple 1 row returns.The gridview will only show the first return, and no more because each return from the SP is labeled as row 1. Is there a way to change my SP or have gridview assign a new row number to the returns?My SP:
