I have a GridView, without using SelectedIndexChanged, how can I retrieve the value of each row from GridView when click on each button in each row?this is my aspx code
[Code]...
I have a few reasons that I need this to happen, but suffice it to say that when I use the event handler for the RadioButtonList the sender object returns as just the RadioButtonList, and I need more information from the GridView because that's how I can uniquely identify which record my RadioButtonList is tied to.I added an "OnSelectedIndexChanged" property to my GridView but it doesn't fire/handle when I want it to. I'm assuming this has something to do with the way the GridView is designed to work. I also thought about using a hidden field, but I can't add it to the RadioButtonList so it won't help unless it's global. The problem with it being global is that I can't set the value uniquely to the record that has it's RadioButtonList being altered.
View 1 RepliesI have been looking for a solution to this for a while though and seen many posts that show me how to do it but yet I cannot get my SelectedIndex Changed event to fire when the DropDownList is changed.The DropDownList AutoPostBack is set to True,[code]
View 2 RepliesI have a GridView which you can click on a row and it should call the SelectedIndexChanged method (which updates another part of the page based on which row was selected). I have done something similar to this before and it worked, but I can't seem to get the SelectedIndexChanged part to be called for some reason.The page is held in a master page which has a form runat="server" tag, and an <asp:ScriptManager> tagI am using e.Row. Attributes.Add("onclick", ClientScript.GetPostBackClientHyperlink(Me.gridMessages, "Select$" & e.Row.RowIndex)) to allow the SelectedIndexChanged to fire by clicking anywhere on the row.To check that the code does work apart from that, I added a CommandField with a SelectButton and that successfully fires, but i would prefer to find a solution without having to use that.[code]

I am databinding my gridview in VB code behind. Because of this I know I can not refer to the NewValues when text is entered into one of the edit boxes. I need to retrieve the value of a column in the RowUpdating event.I have tried to do this in a multide of ways, but each of my changes ends up breaking something else.None of these three methods is working....
Dim DT34 As String = DirectCast(GridView4.Rows.FindControl("Textbox1"), TextBox).Text
Dim TB1 As Label = GridView4.Rows(e.NewEditIndex).Cells(0).FindControl("Label1")
Dim tb1 As TextBox = GridView4.Rows(e.RowIndex).Cells(0).FindControl("TextBox1")
Dim IDVal As String = tb1.Text
In the following code, I am believe it is finding the control but it is not returning the value that was entered into the textbox.
Dim tb As TextBox = DirectCast(GRD4.Rows(index1).FindControl("TextBox1"), TextBox)
updateDescription = tb.Text
My field has been converted to a Template field in the Gridview instead of Boundfield.
I have a .aspx search screen that displays the results of the search in an asp:GridView component. There can be up to approx 1000 records returned by the search. I want to implememt paging on the grid so that only 15 records are displayed at any one time and the user can page through the results.
I am retrieving the records by passing search parameters to a WCF service which returns a List of particular entity objects. I create a Datatable and insert one DataRow per entity object from the List. I then bind the grid view to the Datatable.
This is how my grid is defined in the .aspx page:
<asp:GridView ID="gridCat" runat="server" AutoGenerateColumns="False" DataKeyNames="CatalogueID"
HeaderStyle-CssClass="fieldHeading" RowStyle-CssClass="fieldContent"

Is there a better way to do this (or am I doing it wrong)? If not, which of the 3 options do you think is the best? I'm leaning towards option 2 as I don't think option 1 is performant and I don't want to be sending loads of unnecessary data back to the browser as per option 3.
I know how to loop through a GridView and extract each row using the for each loop as below, but I was looking for a easy way to loop through the datagrid and say extract the last 20 rows? Is it possible to go through in reverse order in vb.net?

I have a situation where I'm allowing users to enter new values into a combo box or selected existing values from the combo box's drop-down list.

View 3 RepliesI am using VB 2010 express edition, using windows form, i set my access database using the database connection wizard, and then use a combobox and bind it to the database using the properties windows, while other fields of database (set in textbox form), i drag it to my form. Running it, the values of textboxes are correct when i changed the value of my combobox. I want to use these values in textbox in drawing circle, whenever i change the value of combobox, the circle will also change using the combobox selectedIndexchanged event, my problem is, the value in textbox does not update in order to draw the circle, i have to use lostfocus or leave event to correct it. I make also a combobox and textbox not using this Ado.net(correct me if im wrong), it is working using the selectedindexchanged event only, what seems be my problem,
View 1 RepliesOn a form I have a DataGridView. Inside this DataGridView i have several columns of which one is combobox and the others are textboxes.The combobox column is populated with values from a MySql database table using a query. So far so good. What i want next is to populate a certain textbox from that DataGridView, automatically after a value from the combobox is selected. When a value is selected from the dropdown list of the combobox, that value is used in a SQL query to find the value that will be displayed in the textbox.All the textboxes and the combobox are inside the DataGridView!)I did this using DataGridView EditingControlShowing event because a DataGridViewComboBoxCell does not have aSelectedIndexChanged event.The value is displayed correctly in the textbox, but the problem is that the value selected from the combobox disappears after the selection, and the combobox remains empty. I need the value to remain in the combobox after it was selected and after the corresponding value was inserted in the textbox!Here is the code for this:

For some reason I have always used the SelectedIndexChanged property to take action when something is clicked (I guess because this is the default property? ie when you double click the listbox this is what you get). However I have often come across problems when I try to unselect all the items in the listbox by calling

.net 4.0, ASP.net, vb.net. I've got a usercontrol that is using an obout combo box. The obout is a cascading combobox that has 3 levels to it. when something it selected from the third level of the combobox, it is suppose to fire off a selectedIndexChanged event. This happens the first time that I select the usercontrol. The problem is if i want to go back and select something different. The selectedIndexChanged doesn't fire. I've set breakpoints and the AddHandler ComboBox3.SelectedIndexChanged, AddressOf ComboBox3_SelectedIndexChanged
runs just like it did the first time i select the usercontrol. But the selectedIndex just doesn't fire the second go around. Was wondering what i'm doing wrong. Here is the selectedIndexChanged that is not firing

View 8 RepliesI have two listviews with many items present. When the user clicks an item in ListViewA, I highlight items in ListViewB. I use the SelectedIndexChanged event of A, loop through the items in B and set some highlighting colors, ensuring visible etc. This works fine.However... it would be nice to allow the user to MultiSelect. The problem here is the when selecting 10 items in A (holding the shift key down), the SelectedIndexChanged event fires 10 times, once for each item added into the selection. This is a real pain since my highlight sub then runs 10 times and it takes 10 times as long.Now... I had a plan to deal with that, I detect the shift key being held down and inhibit the event until its raised. That works fine too.But... if I have 10 items selected, and then I click one new one, so 10 are being deselected and one being selected, the SelectedIndexChanged event fires 11 times. So my situation has not improved. Any ideas how to wriggle out of this?

How can I ensure that the event method is called?
I have a ListView that populates some fields whenever the user selects an item. However, if they change the data in the fields and then select a new item without saving, I want to display a message box that warns that their changes will be lost, and asks them to confirm whether to continue. Sounds simple.
Unfortunately, the ListView's SelectedIndexChanged event cannot be cancelled, and it's actually called for each change in the selection. So, for example, if item 1 is selected and the user then selects item 2, the event is called twice: once to remove the selection of item 1, and then to add the selection of item 2. If you go from having one item selected to having five (for example), the event fires to remove your original selection, and then again for each of your new selections - six hits in all.
Obviously, this makes it a bugger to determine when the event should be cancelled and reset back to the original. I obviously don't want my message box appearing six times....
