GridView Selects Wrong Row For Editing
Aug 4, 2011
I have a searchbox and when I search for a record it is fine the records shows up however once I click edit on the gridview the page does a postback and all the records show back up with the first record selected for editing. How can I disable this post back or make it when I click edit all the records do not display again?
VB.CodeBehind
Protected Sub btnClear_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnClear.Click
txtSearch.text = ""
sourcegridview.DataBind()
End Sub
[code] .....

I have a GridView and, using a fairly common method, I'm using a FooterRow and TemplateFields to provide the missing insert ability. So far so good.The footer contains a TemplateField with a LinkButton to provide the postback that does the insertion. In the handler for the LinkButton's click, the Insert() method is called on the ObjectDataSource that the GridView is bound to. The ObjectDataSource's insert parameters are populated in the handler for its Inserting event. The code for all of this (abridged) looks like this:
Markup:
<asp:GridView ID="gvComplexRates" runat="server" AutoGenerateColumns="False"
DataKeyNames="id" DataSourceID="odsComplexMileageRates"
EnableModelValidation="True" ShowFooter="True">
<Columns>
[code]....
The first of these shows a tag of td. Which makes sense. The second shows text of "10" which is the content for the row above the footer.

This is driving me out of my mind. My Gridview returns the wrong rowindex after sorting or filtering. I am using a detailsview to edit the selected record however I found out I was editing the wrong record. I am using this statement to retrieve the selected record from the gridview
DetailsView1.PageIndex = GridView1.SelectedRow.DataItemIndex however this only returns the correct index if the grid stays in the original form, meaning not sorted or filtered. I guess the statement returns the index with respect to the gridview not the actual table. First of all is this this a .NET bug? and second of all how do I retrieve the correct record to edit it in the detailsview either by getting the correct index or a key such as AssetID in my case. I am using VisualStudio 2010 Professional and the code is in VB. Please do not give me C# as I don't use it.

how I can simply dynamically edit a cell in a gridview. i.e. Just click on it and type, and post the changes when I lose focus to the gridview?I have tried defining a cell as a template control (textbox) and get it to display and let me type in, but it does nothing beyond that. I cannpt even get the default value from the underlying dataset into that cell.

All my collegue programmer asked me to do is disable the editing of a checkbox in a grid. I have tried to set the column to readonly, does not work, does not seem to have any effect:
dgvPatients.Columns(0).ReadOnly = True in the Load handler of the containing form.
The code happily goes to the compiler, but the GUI still allows editting.
And I tried catching the CellClick event, and in the handler do nothing. It gets there, but still it does, what it did, editing that checkbox. Propably some other event or the parents of the class event is still changing the checkbox.I used dgvPatients.CellContentClick I have also set the property:
In the properties, gridview, edit columns, select that column, bound columns properties, ReadOnly to true in the designer, it let me down. Still the gui lets the user change that check box. what I am doing wrong? My collegue will be in tomorrow, may-be he knows but it bites me this problem.I have searched on the internet, I have spend quite a lot of effort in it, and I am out of options now. What is this??

I have a series of GridViews in a Tab Panel - databound to a generic List of Business Objects.
The columns in the Gridview are all similar to the following:
<asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName">
<ItemTemplate>
<asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName")

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

How can I set a group box to behave the same way visual studio behaves as you are typing code. Meaning, as you type code, a small window appears with code suggestions, and as you type, it highlights the best match with your text. How can I create this functionality with a group box and rich text box that I type in? By the way, I put the group box and rich text box in separate windows.

I have a Stored Procedure that I'm trying to use in my vb.net program to fill a form with multiple datagrids.The Stored Proc looks like this:
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
[code]....
My question is how do I address the multiple select statements in the return values of this Stored Proc? The way this is written will it return all the values from each select? or just the first one?

I am creating the items in a combobox in my code behind. I am setting the display member and the value member. When the user makes a selection from the combo box, I need to get the value of the selected item. I have written some code, but when I step through it, it says that the selectedvalue is Nothing.
Here is the code where I am creating the items in the combo box:
Do While drReader.Read
cboTheater.Items.Add(drReader("TheaterDesc"))
cboTheater.ValueMember = CStr(drReader("TheaterID"))
cboTheater.DisplayMember = CStr(drReader("TheaterDesc"))
Loop
In the selected index change event for the combo box, I am doing the following:
Dim strTheater As String
strTheater = CStr(cboTheater.SelectedValue)
When I step thru the code, strTheater is Nothing

I have a form on which the user selects a file using an openFileDialog. The selected filepath is then processed, which may take 10-20 seconds before the user is presented with the results.I'm finding that the once the user selects the file (clicking the OK button on the openFileDialog), the openFileDialog remains open until all of the processing going on in the background is completed. Once the processing has finished the openFileDialog disappears and the results are shown.The problem is that whilst the openFileDialog remains open on screen, it is not apparent to the user that anything is happening in the background. I do actually have a textbox which updates the user with messages showing the progress. However the openFileDialog hides the messages until it closes, essentially making the progress messages useless.What I'm trying to do is have the openFileDialog close immediately that the user selects a file. Then the processing can continue without the openFileDialog obscuring my form.

In my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2
I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also. For instance, on Row1, if comboBox1 = A, combox2 = B
Then on Row2, if comBox1 = Y, comboBox2 = Z
However, when I change Row1, Row2 is also changed to reflect what was chosen in Row1. Is there a way I can tailor it to each specific row?
