I have a UserControl inside the ItemTemplate of my FormView and I need to access it in order to get an event fired off. As the UserControl is inside the template, my event cannot see it!
View 4 RepliesI've been searching all day for a solution to this, but nothing has worked.
Here's my scenario: I'm binding the gridview to a datatable. One of the columns is a textbox that will accept user input.
When a "submit" button is clicked, I need to loop through all the rows, get the textbox's text, and add them all together. Simple, right?
I've tried the following (this is on the "submit" button's click event):
[Code]....
The itemtemplate looks like this:
[Code]....
The txtDays.Text property is ALWAYS empty. UNLESS I assign it a value w/in the control. But then it's ALWAYS that value. I need to get the value of what the user enters.
I have added a table to my FormView Edit template for structure and a button that pops up a form for information.
When the button is clicked I want a check box in neighboring cell to become checked. But I am having problems in the VB code behind, establishing the name of the check box to change its state. Its something like this....
FormView1.ItemTemplate.(CheckBox1.Checked = True)
I have something like this:
[Code]....
[Code]....
This does NOT work. What's wrong here?How do I accomplish my goal? I MUST use the Button1_Click event for this one.
I keep getting a null reference when I try to access a listbox inside the EditItemTemplate of a formview. I check the mode before accessing the control (Formview1.CurrentMode) to make sure it is in edit mode and even set it manually to edit mode again! But formview1.findcontrol("blah") returns null. Formview1.EditItemTemplate does not have a FindControl method, not sure what else to try.
View 1 RepliesI would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.

Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
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.text
In almost all cases, my edit template and insert template in the formview are the same.
So instead of copying pasting the same markup, i decided to put it in a user control. The display works fine, however, the databinding doesn't work anymore. It works fine if I put the markup directly in to the formview template.
I have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.
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 trouble trying to access a UserControl I created and placed inside the EditTemplate of the ListView. How is it done? I've tried to access it at the ListView's ItemDataBound, ItemEditing and Databound with the following code with no luck:
ucEditTask = DirectCast(lvTimeEntry.FindControl("ucEditTask"), UserControl)
I have a radiobutton inside an itemTemplate in datalist , and i'm binding this radiobutton dynamically from database, the problem is that all the radiobuttons generated are selectable at the same time which is wrong. (Multiple radiobuttons selcted at the same time)

I have an ItemTemplate inside a listview with a linkbutton wrapped around three table rows. The linkbutton is supposed to make the whole rows clickable but this only works in IE. Does anyone have an idea about why? The link works if I move the rows out of the linkbutton and write some gibberish text instead, but that's not what I want.

What it does is to select the right value to a ListBox that is databinded with values inside a DetailsView
here is the rest of the code:

Is there an easier way to achieve the same thing perhaps without any code behind?
Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:
[Code]....
<asp:DataList ID="listSearchResults" Border="1" BorderColor="Black"
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="LabelSubUpdateID" runat="server" Text='<%# Eval("UpdateID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>

I have a GridView with two templatefields, one with a DropDownList and the other with a TextBox, both loose their values once I hit the "update" button. Is it any way I can make the controls keep the values?
View 8 RepliesI have a ListView showing just a list of concatenated strings obtained from different field of the objects of the datasource.
A LinkButton (with CommandName="Edit") in each row Event handlers for OnItemDataBound and OnItemEditing
A UserControl in EditTemplate.
Now the problem is, I don't know how to use Bind expression in the UserControl. I mean, how to populate this usercontrol when the linkbutton is clicked? (I tried capturing the control in theOnItemEditing handler. But FindControl returned null, as that handler is called before going to edit mode.)
I have a usercontrol with a datagrid that is used throughout my web application. The datasource is passed in a public method from the master page to this usercontrol, as the data selection is different on each page where this usercontrol is used.But by doing this, I'm having a problem with paging, as the datasource is lost after postback. I can't do the data selection in the usercontrol itself as the dataset is passed as a parameter.
