How can I access to MyGridView programmatically ?
I have gridview in my page that users can edit their data in gridview... and in this gridview I define label that I want when users click on Edit button it change label3.text:
below is code:
<asp:GridView ID="GridView1" runat="server" CssClass="DGridView1"
        AutoGenerateColumns = "false" Font-Names = "Tahoma"
        Font-Size = "9pt"
        HeaderStyle-BackColor = "#e0e0e0"
        OnPageIndexChanging = "OnPaging" onrowediting="EditCustomer"
        onrowupdating="UpdateCustomer" onrowcancelingedit="CancelEdit"
         GridLines = "Both" OnRowDataBound = "OnRowDataBound"
>
And .cs:
protected void EditCustomer(object sender, GridViewEditEventArgs e) {
Label Label3 = (Label)GridView1.Rows[e.NewEditIndex].FindControl("Label3");
Label3.Text = "neda";
GridView1.EditIndex = e.NewEditIndex;
BindData();
BindData1();
}
but here when I click on EditCustomer it doen't change label3.textÂ

This does NOT work. What's wrong here?How do I accomplish my goal? I MUST use the Button1_Click event for this one.
on my page, there are two listboxes,

Based on the selection of SchoolID in listviewSchools, the ListviewStudents will be filled with the data.
SchoolIDLabel is in the ItemTemplate of the ListviewSchools. The following works for insertitemtemplate
Dim txtTitle As TextBox = CType(ListView1.InsertItem.FindControl("txtTitle"), TextBox), but i can not Access a control inside the ItemTemplate of a listview.
How do you go about creating a complex servercontrol frontend?...I can't imagine you do Controls.Add() in the .cs files to add in divs, classes etc Can you embedd an ascx to make it easier to style?
View 5 RepliesI have a gridview that contains check box in first column for each row. I also have a check box outside the grid view called >>>>
<asp:CheckBox ID="chkSelectAll" runat="server" Text="Select All" AutoPostBack="true"
OnCheckedChanged="chkSelectAll_CheckedChanged" />
I either can select more than one checkboxes from gridview then click on a button to get the number of checkboxes selected OR I click on SelectAll checkbox ( which is outside the gridview ) which check all the checkboxes in the gridview and give me the number of checkedboxes. When I select inidividual checkboxes inside the gridview, th e count of number of checkboxes is correct ( displayed in a lable ) However;
When I click "SelectAll" check box, it give me total of all checkboxes chekced in the
gridview + 1 ( extra ) I am trying to get rid of this extra one by checking if this "Allcheckbox" is selected to so I subtract one from the total count .. like this
// java code ... code not shown does capture the total count into c variable
varAllChecked = document.getElementById('chkSelectAll');
if (varAllChecked.checked== true)
litCount.innerText = c - 1;
else
litCount.innerText = c;
I have a user control which is used to display search results. The HTML for each result displayed will vary based on the type of result being displayed: "contacts" are displayed in one way, "news articles" are displayed in another, etc. There are around 10 different types of results that are all marked up differently when they get to HTML — so I need around 10 or so different templates for individual results that I can choose between based on the current item being displayed.
I'm using an asp:Repeater to display the results, but I don't know how to select the appropriate template within the asp:Repeater <ItemTemplate>. Ideally I'd like the ASP to select the appropriate template to use based upon the object type being passed in via the searchResultsRepeater.DataSource — but unfortunately I can't use switch on type (see this blog entry for C# switch on type). I can however just pass through an enum value for the type of result being displayed.
In the backend C# code I have an abstract inline SearchResult class, and children of that class like ContactSearchResult, NewsArticleSearchResult, etc. The searchResultsRepeater.DataSource would then be bound to a List<SearchResult>. Each SearchResult contains a ResultListingType type field which gives the type of the listing to be displayed.
Attempt 1: using control flow inside the ASP itself
My first attempt was something like this:
<asp:Repeater ID="searchResultsRepeater" runat="server">
<ItemTemplate>
<div class="item">
<% switch (DataBinder.Eval(Container.DataItem, "type")) { %>
<% case ResultListingType.CONTACT: %>
<p><%# DataBinder.Eval(Container.DataItem, "firstName") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "lastName") %></p>
<% break; %>
<% case ResultListingType.NEWS: %>
<p><%# DataBinder.Eval(Container.DataItem, "newsHeadline") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "newsDate") %></p>
<% break; %>
<% Case AnotherTypeOfListing1: %>
<% Case AnotherTypeOfListing2: %>
<% Case AnotherTypeOfListing3: %>
<% Case AnotherTypeOfListing4: %>
<% Case AnotherTypeOfListing5: %>
<% etc... %>
<% } %>
</div>
</ItemTemplate>
</asp:Repeater>
Unfortunately, this doesn't work:
"switch" and "if" both give "invalid expression term" inside the <%# ... %> brackets.
"Container.DataItem" gives "the name "Container" does not exist in the current context" inside <% ... %> brackets.
Attempt 2: setting asp:PlaceHolder's to Visible = False
I found something that looked useful at how to change the ItemTemplate used in an asp:repeater?. I then tried something like:
<asp:Repeater ID="searchResultsRepeater" runat="server">
<ItemTemplate>
<div class="item">
<asp:PlaceHolder ID="newsResultListing" runat="server">
<p><%# DataBinder.Eval(Container.DataItem, "newsHeadline") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "newsDate") %></p>
</asp:PlaceHolder>
<asp:PlaceHolder ID="contactResultListing" runat="server">
<p><%# DataBinder.Eval(Container.DataItem, "firstName") %></p>
<p><%# DataBinder.Eval(Container.DataItem, "lastName") %></p>
</asp:PlaceHolder>
</div>
</ItemTemplate>
</asp:Repeater>
In my ItemDataBound event I did:
Control newsResultListing = e.Item.FindControl("newsResultListing");
newsResultListing.Visible = false;
Control contactResultListing = e.Item.FindControl("contactResultListing");
contactResultListing.Visible = false;
switch (item.type)
{
case ResultListingType.CONTACT:
contactResultListing.Visible = true;
break;
case ResultListingType.NEWS:
newsResultListing.Visible = true;
break;
default:
throw new Exception("Unknown result listing type");
}
Unfortunately this doesn't work because ASP seems to still be running the contents of the PlaceHolder even after I set Visible = false. I get the error "DataBinding: 'usercontrols_ResultsListing+ContactResultsListing' does not contain a property with the name 'newsHeadline'" — i.e. the newsResultListing PlaceHolder is still looking for the "newsHeadline" field, even though that field doesn't exist for the result listing type being displayed.
In fact I've tried a quick test throw new Exception("e"); in my ItemDataBound, and it looks like the "DataBinding" error is thrown even before control flow gets to the ItemDataBound method, so there's really nothing I can do in there to avoid this error.
I suppose I could add every single field to the parent class and leave most of them null in my children, but that seems really ugly.
Is there a way to make this work, or an easier way to vary my ItemTemplate based upon the type of Container.DataItem I'm currently iterating over? I'm very new to ASP so there's likely something simple that I've missed.
Inside repeater's itemtemplate I have a Panel server control.I need to assign special Id for it, because I need to work with some javascript functions that use this Id.
In repeater ItemDataBound event I have this:
pnlButtonsPanel.ID = pnlButtonsPanel.ID + DataBinder.Eval(e.Item.DataItem, "ID");
But this solution is not good because after a postback the page is re -rendered and I lose the new ID. (And I don't want to rebind repeater after every postback)
I tried to set the ID on aspx page like that:
<asp:Panel id='<%# Eval("ID") %>'
and some other variations but always get compile errors.
I am new to Repeater and DataBinding
In PageLoad, I have
var photos = from p in MyDataContext.Photos
select new {
p,
Url = p.GetImageUrl()
};
repeater1.DataSource = photos;
repeater1.DataBind();
In the Repeater control, I have
<ItemTemplate>
<% Photo p = (Photo) Eval("p"); %> <!-- Apparently I can't do this -->
...
<asp:TextBox runat="server" ID="txtTime" Text='<%= p.Time == null ? "" : ((DateTime)p.Time).ToString("dd/MM/yyyy HH:mm:ss") %>' />
...
</ItemTemplate>
But that is wrong.
What I need is to get the Photo object in ItemTemplate so I can do things with it (eg. to display the time as in the second line in ItemTemplate above). Is it even possible to do this in a Repeater?
I have a grid. Inside the grid I have a button which is placed inside an update panel, which when clicked should do something I tell it to do in code behind. The problem is that when I click the button, it ignores the fact that the button is inside the update panel and it refreshes the entire grid, instead of refreshing only the stuff inside the update panel. What I need it to do instead is update only things inside the update panel my button is in, but leave alone the grid.
This is the setup I currently have:
<asp:GridView ID="grv_FieldDesc" EnableViewState="True" runat="server" DataSourceID="ObjectDataSource1"
OnPreRender="grv_FieldDesc_PreRender">
<asp:TemplateField HeaderText="Hidden">
<EditItemTemplate>
<asp:UpdatePanel ID="updp_grids_formula" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:LinkButton ID="Button1" runat="server" OnClick ="Button1_Click">LinkButton</asp:LinkButton >
</ContentTemplate>
</asp:UpdatePanel>
</EditItemTemplate>
</asp:TemplateField>
</asp:GridView>
As you can see in the image below there is a ValidationSummery exists inside a TabPanel.In spite of I haven't changed anything in the default style template which added by the Visual Studio. the validation summery's font is a bit big although its size is normal when it is not in the TabPanel.And the TabPanel doesn't have any style and all the controls which inside it appear in their default size.I wonder if you could help me with any idea about this strange size.
<ajax:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0">
<ajax:TabPanel ID="BasicInfoTab" runat="server"

I have a GridView displaying names from a DB and I have added a checkbox to each row to select certain candidates (code below). This data then gets posted to another page which is where my problem is...What I'd ideally like is to have the CandID value stored against chkSelect in the form so I can then work out which candidates are selected. However, what I actually get in my form is 'gvCands$ctl159$chkSelect=on' for instance. It's not particularly easy
to figure out which candidate is #159 so I'm guessing that's the wrong route to go.

I have a DataGridView with a ItemTeplate column, which has a HTML hyperlink (<a href....>) inside. When a user clicks on a link, a popup with a TextBox is showed to the user. Then the user can type a data. With this data, I must update the hyperlink's text in which the user clicked. All using javascript. The problem is that I don't know how to find the Hyperlink because there will be so many hyperlinks as rows in the DataGridView and they will have the same Id.
How can i find the hyperlink using javascript?

I am having a slight problem with a feature I am trying to get working on a website I am doing. I keep getting the "No data exists for the row/column" error. And the problem appears to be with this line of code:
[Code]....
I have some code with a connection string going to a mdb, the query looks correct to me and I know that the data stored in the table exists but when I run the query in my code it says: No data exists for the row/column.
[Code]....
It has crossed my mind that perhaps the way the data is put into the program is not compatible with the data in the database, I don't know if that is a valid thought though.
I am taking backup for mdb file from source location to destination location.While using file.copy() function,how to check whether the folder is already exists or not.If exists means how to replace new one for existing one.Send C# code for replace new one for existing one.

View 3 RepliesI found this solution to force full postbacks from within an UpdatePanel
<Triggers>
<asp:PostBackTrigger ControlID="controlID" />

but my control is actually inside an ItemTemplate nested in a GridView. Therefore when my page loads, it doesn't find that control.
How can I force a full postback from my control (an asp:LinkButton) from within my GridView?

@Behcode nvarchar(30)
as
begin
select T_name
from House_Info
where Behcode=@Behcode

I use below code to bind data from database in destination pages
 string data = Server.UrlDecode(Request.QueryString["BehCode"]); _cmd.Parameters.AddWithValue("@behcode", data);
