VS 2010 - Own IDs For Checkboxes In GridView
Aug 29, 2011
I got a gridview in place after nutting it out (new to Asp.net WebForms) after asking here. Remember my gridview are being bound to an IList<>. Works fine (code below)
I want to add a checkbox next to each row so users can select those records that they want (not relevant..yet)
However I could not find a way to set the id of the checkbox to the Id of the instance of my class (IList<MyClass> for instance where MyClass got an EntryId member).
This is what I got so far (working fine..just that id's)
Code:
<asp:GridView ID="MyGrid" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:TemplateField HeaderText="Export">
<ItemTemplate>
<asp:CheckBox ID="whatdoweputhere" runat="server" Text="" />
[Code] .....
Another question (related, so figured I'd ask here) is how do I get the checked items in my code behind (got a link button and want to go over the selected items in it's click event).

I am trying to use a check box within a repeater in an asp.net vb application. Basically, i am have an application that allows users to create blog posts and then other users can comment on them. I am using a check box to provide the user with functionality to like the posts comments.
When the user clicks on like, it is supposed to fire the event which will insert or update the users like record. However, this even does not seem to be firing.
I set up the check box within a table within the repeater as follows:
Code:
<td class = "LikeCellRepeat">
Like: <asp:CheckBox ID="chkLikeComment"
runat="server"
ToolTip="Like"
AutoPostBack="True"
[Code] ....
And here is the check changed event:
Code:
Protected Sub chkLikeComment_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs)
MsgBox("like clicked")
Dim CommentItem As RepeaterItem = sender.NamingContainer
Dim HiddenID As HiddenField = CType(CommentItem.FindControl("HiddenCommentID"), HiddenField)
Dim CommentID As Integer = Convert.ToInt32(HiddenID.Value)
[Code] ....
I included a Msgbox in the event to see if i would at least get that and then the problem might be something else, but i don't even get the msgbox to pop up which is why i'm thinking the check changed event is not even firing.
I've been searching the net for solutions on how to get it to fire, but what i've found so far either does not work or i am not using it properly. I saw something about re-subscribing to the event in repeater's on item data bound, and tried to set up that the way they had, but i am not sure if i did it right, as i get an error that says the checked changed cannot be called directly and to use raise event instead...
Code:
Protected Sub rptComments_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rptComments.ItemDataBound
Dim CheckLike As CheckBox = CType(e.Item.FindControl("chkLikeComment"), CheckBox)
CheckLike.AutoPostBack = True
CheckLike.CheckedChanged += New EventHandler(chkLikeComment_CheckedChanged)
End Sub
I have been trying to get this to work for about a week now with no luck

I have an ASP .NET GridView with Paging. One column in it has a CheckBox. In a certain scenario, I want to uncheck the checkboxes that are checked.
foreach (GridViewRow dr in gvMyGridView.Rows)
{
if (dr.RowType == DataControlRowType.DataRow)
{
if ((CheckBox)dr.FindControl("chkIsApplicable") != null)
{
((CheckBox)dr.FindControl("chkIsApplicable")).Checked = false;
}
}
}
But unfortunately because of Paging only the records that are currently shown in the Grid can be accessed in this way. I want it to apply to ALL the items in the GridView. This should happen client side and when the user commits will get saved to the database.

I have checkBoxes in my Gridview templete columns called "Category A" and "Category B". I want Select-All functionality, i.e. when the user checks the Select-All check Box in category A column, all the checkboxes must get checked under that column. Same for Category B. I am trying with the code below. The problem with my code is, it selects all the check boxes in the entire gridview, "Category A" as well as "Category B"s checkboxes. But, I want only checkboxes selected under the same column.

have a gridview with a bunch of checkboxes. I would like to restrict the selection based on a value I get back from the database. I am able to do this on the serverside but it is very cluncky. Is there a way I could do that using javascript and ajax or just a more elegant way to approach this. The gridview is in a usercontrolMy code right now -

I am running into a problem getting a value from my Grid View based on the selected checkbox. I have a grid view that is populated by database based on search criteria. However once that Grid View is populated, I would like to be able to select multiple ID's from that view. My coding experience isnt the greatest as I am still fairly new to all of this.
<asp:GridView ID="GridView1" runat="server" DataSourceID="ObjectDataSource1"

I am trying to implement a gridview with some checkboxes to allow users to select the rows that they would like to insert into a file selected from a dropdown list. am working on being able to select the rows from the grid but not having much success. I can get it to recognise each selected row but when I place them in a dataset it only stores the last checked gridrow. It's probably something simple that I'm missing y code is
protected
void Insert_ButtonClick(object

I hav a prob of checkboxes' checks not being registered...as explained below :
I have a gridview which is being populated using datasets.
[Code]....
I have added a column of checkboxes it using a TemplateField
[Code]....
And I am using a button to count the number of checked checkboxes.
[Code]....
I am viewing the value of session variable under at check.aspx
The Problem is that no matter how many checkboxes I check they are always counted as 0. The 'check' just doesnt get regsitered in the gridview.
After quite certain testing, a few things are clear
The checkboxes are being discovered by the counting loop fine.If I mark a cell as checked in the dataset before binding, then that check does get registered and thus is counted. Any thing I am missing ? Do i have to update something ?

Im trying to input the value in the table into the checkboxes but i keep getting an error that states: "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"When i do a quick on this part of the code :"DirectCast(GridView1.Rows(i).FindControl("DescriptionA1"), Label).Text", i get "Run-time exception thrown". This is my first time trying something like that, i have search for solutions but now im more confused than ever.

I have situation where I have to show checked CheckBox in a GridView. I have three tables
1) Menu Items ( Fields: menuID, menuName, menuLink, .....)
2) User Types (Fields: userTypeID, userTypeName, ...)
3) User Menus (Field: menuID, userTypeID )
I have a screen to add new Menu Items where I am showing a Grid That has two columns
1) CheckBox and
2) User Type
I have to check CheckBox in order to Link that User Type with the Menu Itme. I am done with Add Screen. Here is the Code:
(aspx)
<asp:GridView
ID="gridView_UserTypes"
runat="server"
AutoGenerateColumns="False"
DataKeyNames="userTypeID"
Width="60%"
EmptyDataText="">
<HeaderStyle
CssClass="gridHeader"
Wrap="false"
/>
<AlternatingRowStyle
CssClass="gridAlturnateRow"
/>
<RowStyle
CssClass="gridRow"
/>
<Columns>
<asp:CheckBoxField
DataField="userTypeChecked"
HeaderText="Select"
ReadOnly="false"
Visible="true"
/>
<asp:TemplateField
HeaderText="Select">
<ItemTemplate>
<asp:CheckBox
ID="userTypeSelector"
runat="server"
/>
</ItemTemplate>
<ItemStyle
HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
<asp:BoundField
ItemStyle-HorizontalAlign="Left"
DataField="userTypeName"
HeaderText="User Types"
HeaderStyle-Wrap="false"
ReadOnly="True"
SortExpression="userTypeID">
<ItemStyle
HorizontalAlign="Left"></ItemStyle>
</asp:BoundField>
</Columns>
</asp:GridView>
(Code Behind)
foreach (GridViewRow row in gridView_UserTypes.Rows)
{
// Access the CheckBox
CheckBox cb = (CheckBox)row.FindControl("userTypeSelector");
if (cb != null && cb.Checked)
{
// First, get the UserTypeID for the selected row
int userTypeID = Convert.ToInt32(gridView_UserTypes.DataKeys[row.RowIndex].Value);
if (selectedUserTypeIDs == "")
{
selectedUserTypeIDs = userTypeID.ToString();
}
else
{
selectedUserTypeIDs = selectedUserTypeIDs + "," + userTypeID.ToString();
}
userTypeCount++;
}
}
Now I am passing selectedUserTypeIDs along with other details to my Stored Procedure and adding those UserTypes for newly Added menu. It works fine for me. Now I want to show checked CheckBox in Edit Mode.
