Forms Data Controls :: Label From Dropdownlist In Itemtemplate?
Nov 25, 2010
I have a dropdownlist - ddlGroupName. Next to it, I have a Label - lblGroupName. The dropdownlist is bound to an SQL table, and displays the appropriate group depending on the primary key (contracters, suppliers, etc etc). When the page loads, I want the Label to display whatever is in the dropdownlist, then I can hide the dropdownlist and am just left with the label. I was using "lblGroupName.Text = ddlGroupName.SelectedItem.Text;", but intellisense doesn't seem to acknowledge the controls when they're in an ItemTemplate.
Used onprerender a lot with dropdownlist boxes never used with textboxes.I have two currencies used in my application, want to format before i show to use.
This is my gridview structure I need two things from this1) For example in Label1 shows 50 then In Text1 I need to check the value is less than or equal to how to validate in client side in adp.net validation or javascript...? Like this same for second Item template also I need validation.. Like this I have some 10 itemteplate....2) On button click I need to save the value of Text1 and Text2 in database.. how would be my Insert statement in button click..
I'm trying to change the text of a GridView label in an ItemTemplate and I am having some issues. I searched all over and can't find a solution. This is what I am trying to do...
I have a GridView that has a comment field. Normally when the page is rendered the comment field is truncated using a truncate class that limits field length. The full contents can be displayed in a tooltip when the comment field is hovered over. That part works fine.
I also have an export to Excel class that will take the Gridview and export it to Excel and that part works fine as well...
Now the issue... Because of the truncated field, when I do an export it will export exactly what is in that field, the truncated version of a comment. When the export button is clicked I need to change the .text value of the label that is in the GridView ItemTemplate
From this truncated version...
[Code]....
And then back again after the export routine is complete.
I have accessed the contents of a label before using FindControl but never set a value, is this possible? Also, I have captured what is in the comment field on RowDataBound but by that time, it is already truncated.
I was wondering if anyone could help me. I have a template field which has four itemtemplates that each hold a label in a gridview. These labels are always constant with the same strings. What I want to do is change the css formatting of these four labels depending on the value of a column. So the css formatting would have to be done for each row, not the whole column. I bind the gridview to a dataaccesslayer so there is no sqldatasource on the page. Does anyone have any idea how to do this and where it would be done. I will have the dataview with the data sorted in the correct order. The actual column that is used to alter the CSS will not be in the gridview although I could assign it to the datakeyname if that makes it easier as the data is not sensitive.
on SelectedIndexChanged event handling of DropDownList in ItemTemplate of ListView. I put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, with code behind, but only to get Compiler Error Message: BC30456: 'DropDownList1_SelectedIndexChanged' is not a member of 'ASP.webform1_aspx'. How do I make it a member? When I do not put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, BC30456 does not pop up, but nothing happens when dropdownlist selected item is changed.
What I have is a GridView with a DropDownList in an ItemTemplate (not an EditItemTemplate). My datasource is not a control, rather in the code-behind.
[Code]....
My main problem is that VS is not seeing that I have the dropdownlist, meaning I can not access any of the events in the code-behind. What I want to do is, when the value of the DropDownList is changed (SelectedIndexChanged), I want to grab the value of the RowIndex of the GridView.
I'm trying to do a relatively simple thing, but just cannot get it to work. I'm trying to find a dropdownlist within a ListView ItemTemplate within Page_Load.
I read your article on ASPSnippets and everything worked great. I am having one problem and this is preventing me from moving forward. When I select the edit for a row (I only have two columns), the drop down comes back blank (no records). I have looked at the code multiple times and can't see where I made a mistake. is it possible to control the width of the drop down list? I can't tell if the column automatically adjusts because I am not returning any records.
using System; using System.Collections.Generic; using System.Linq;
I have done the itemtemplate and edittemplate,when I click on the button in itemtemplate, the edittemplate will show.But that row in itemtemplate will disappear.How can I keep that row in itemtemplate and ecotent in edittemplate both appear?
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:
i am using visual studio 2008 vb. i have a dropdownlist in my detailsview populated with product id. when i select an id, the product name will appear on a label. however, when i change the product id in the dropdownlist, an error occur "Conversion from string "ProductName" to type 'Integer' is not valid." Here's the code file.
Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim lbl As Label = DetailsViewOrderDetails.FindControl("Label4") Dim ddl As DropDownList = DetailsViewOrderDetails.FindControl("DropDownList1") lbl.Text = ddl.SelectedValue("ProductName").ToString() End Sub
I need to have it required where the selected value in a dropdown must match the label "labelCurrentTime."
This label gets its value from DateTimeNow.ToString with h:mm tt format
The values in this dropdown are just a collection of listitems. They are not coming from a database.
So for example, the user must select "9AM" when the labelCurrentTime displays 9AM. If the user selects any other time, the user will receive an error message.
i write css like above for datalist label. but it is not working. which way i have to write cssclass to binding datalist. as i notice you have use css class at jquery to set value like below.
Am having one gridview. In that there is some details and one hyperlink (for Mail) and one Label (Mail Status).
The Mail status label have default value Not Sent for all fields. If i click the Mail link and send mail to the corresponding person, then the Default label value will be automatically changed its text to Sent.
