how i add DropDownList in edit mode of DataGridView by DataSet through code not visible?
As we know that by default Every Column in Edit mode is a TextBox I want to replace this to DropDownList through code.
I'm trying to programatically populate some dropdownlists inside a formview in EDIT mode, like this below.
[Code]....
I orginally had this running as part of the pagelaod event, but I'm thinking that b/c the page loads first, it doesn't populate the fields in EDIT mode until after the data is saved, and then page is reloaded. Now it knows it's in "Edit" mode. Am I thinking clearly here? Not sure if this is the order of things. So I thought I should just use a formview_modechanged (or similar event) so when the user switches modes, it populates the fields - but I'm not sure which event I should use. I've tried "Modechanging", "modechanged", "prerender", etc, but with no luck. Here's my new code... not sure what's up? Is it simply I've got the wrong formview event? Or am i missing something? Is there an easier/better way to accomplish this?

I have gridview that has month as a column. When the user clicks a row's edit button, that row goes into edit mode. I have created a drop-down list for month in edit mode with the values 1-12. Right now, the drop-down list shows 1. I would like it to show the current value for that row. How do I do this? Here's the code for my gridview:

This is my first post on this forum. I have a Gridview with the following Columns
1. Edit Column
2. User_ID (Read Only)
3. Email (Read Only)
4. Role ( A Dropdownlist with 2 list Items namely "Admin" & "QA Lead")
I have used wizard to populate a "Gridview" and the embedded "Dropdownlist" control in it. This is my reference: [URL] My Problem: The Data populates perfectly in Grid and Dropdownlist. But, when I Press "Edit" button the Dropdownlist goes into edit mode in the form of a "Texbox". (i dont want this) I still want it to be an editable dropdownlist.

I have a Gridview showing the MemberLastName, MemberFirstName, MemberBirthYear, MemberGender, MemberRelationship.
During Edit mode, I have managed to display a DropDownList for the Relationships.What I am trying to achieve now, is that, based on the Gender of the member I would like to limit the items in the Relationships dropdownlist.
e.g if the Gender is Male, then only display Male Relationships
What is the best way to achieve this scenario?Here is my snippet of code for the event. The code is commented out as it throws an exception.

I have a grid view with edit and save buttons when I click on edit it is letting me edit it and if I click on save it is lettingme save the data that I have edited.
The thing is after save is done it is showing the data in edit mode i.e <edit item template > mode I am still seeing the textboxes if I refresh the page then I am seeing it normally.
How can I stop the gridview to show edit mode after the save is done?
- I want to put multiple rows of a gridview into edit mode
- I have not found any easy method to accomplish this task. I found a way to programmatically put a gridview into edit mode, but in testing the code below it works for only 1 row at a time :

View 1 RepliesI am using a DataGridView and have a master table which contains values which different tables related to the master data, i.e. StatusID =1 in master table = TrailerStatus (1, 2, 3, 4 and their descriptions) are in a related table. I am able to retrieve the values from Table B 1 = Empty, 2 = Rejected, 3 = Onsite, etc. However, I don't know how to relate the master table StatusID = 1 to default my dropdown list from the relational table 1, 2, 3, 4.
I have been fighting with this for quite some time and just have not found a solid example of how to do this. I actually have two dropdownlists which will need to be correctly wired in order for my application to work.
This will also be an editable dataGridView but I will tackle that challenge once I get this first hair plucked from my butt.
There is some code-behind which doesn't work at all pertaining to a ;; gvSCACDetail_RowDataBound ;;
but I dont' think I can even get the code to compoile when this is not commented out.
Here are some of the details:
<td style="width: 700px; height: 20px">
<asp:GridView ID="gvSCACDetail" runat="server" AutoGenerateColumns="False" AutoGenerateEditButton="True" DataKeyNames="trailerid,locationid,scacid,statusid,capacityid" AutoGenerateDeleteButton="True" DataSourceID="SCACDetailView" Visible="False" Width="698px">
<PagerStyle CssClass="centerh" HorizontalAlign="Center" />

I have a Gridview that handles double clicks. On a double click, the selected row goes into Edit mode, which means in my case that edit controls (textboxes, checkboxes and dropdown lists) become visible, and display controls (labels) become invisible. On Page_Load the values in edit controls get saved. Now my question is this: how can I get out of the edit mode if I don't want to save? Can I e.g. handle Escape key? BTW, I use C#.
View 3 RepliesI am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?
This is what i have using VS and VB: formview that is bound to a sqldatasource. In the formview i set up three panels and the visibilty is controlled by three buttons. I want to be able to click the edit link button and have the panel that is visible in readonly mode be the one visible in editmode
View 6 RepliesEven though I searched for a similar posting (and couldn't find it), I am certain that someone must have raised this question in the past.
I am relatively new to the .net world and I am using VS2010/SQL Server 2008. I can't seem to find the problem, but when I click on the "edit" button I get a postback but I get the ItemTemplate again.

How can I set a particular row into edit mode in code? Like when the Grid loads up I need the last row to be in Edit mode.
View 3 RepliesI have a gridview and a template column:
<asp:TemplateField HeaderText="Active">
<EditItemTemplate>
<asp:CheckBox ID="chkbxActive" runat="server" Checked ='<%# Bind("Active") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblActive" runat="server" Text='<%# Bind("Active") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
The item "Active" is a bit from the database And for the RowDataBound:
Const HeavyCheckMark As Char = ChrW(&H2714)
For Each row As GridViewRow In gvProductCodes.Rows
If gvProductCodes.EditIndex = -1 Then
' Selects the text from the Label which is inside the GridView control
Dim lblActive As String = CType(row.FindControl("lblActive"), Label).Text
lblActive = lblActive.Replace("True", HeavyCheckMark)
lblActive = lblActive.Replace("False", "")
'Replaces the text in each Label control
CType(row.FindControl("lblActive"), Label).Text = lblActive
Else
Dim chkbx As CheckBox = CType(row.FindControl("chkbxActive"), CheckBox)
End If
The check mark works fine when not in edit mode. But when in edit mode, the row that is being edited works as expected. But the other rows now show True or False. I want them to have the const HeavyCheckMark in it instead.
I created a sample gridview. However, when I clicked edit mode in one of selected row, it will run away. I need to use the mouse scroll up and down to find that row. As well, once finished the edit (clicked update button), it will run away again. I also need to find the editted row by using the mouse. How do I fix the position?
Furthermore, I also want to fix the header. If I scroll down, the header row will be on the top where ever I scroll to.
I need to display data somewhat like this:
Student Name: John
Exam Grade
MidTerm1 A
MidTerm2 B
For this, I defined a class 'Student' that has the properties StudentName[String] and Exams [a list of ExamGrade objects which has the Exam and Grade properties]. And I am using nested listviews to display the data. Here is the markup for the ListViews:
[Code]....
And the StudentInfo class looks like this:
[Code]....
And Exam class has just two properties.
Now the issue is that I have to press the Edit button [link button] twicw to get the EditItemTemplate. Even then I would get the blank textboxes. So what should I do to make the EditItemTemplate appear on the first click and the TextBoxes to appear with the existing data?
I've got a DatalList control on a page that I intend on using for Editing Items. I've added a button control into the Item Template with CommandName="Edit", and when click the button on the item, the page Posts Back and continues to display the ItemTemplate for that item.
Here's what I've got...
[Code]....
Edit mode does not run all the times I have a gridview with custom edit (I have my own textboxes placed in the EditItemTemplate for updating). When the user clicks the Edit button, the gridview goes into edit mode with no problem. In RowDataBound handler, I have the following code which checks if the edit mode is in process then an additional function will be called.
[Code]....
The problem is, I noticed that RowState and function are NOT called every time the GridView goes into edit mode but it goes every other line!!! For simplicity, I have blocked the function and put direct code. I have also tried the Edit functionality provided by the GridView, and surprisingly, it is NOT working!! Notice that in both ways, the gridview is displayed in Edit mode and it does display the
Update Cancel buttons in my second try. It is working fine in all alternate rows! I hope it is clear.
