Forms Data Controls :: Access Link Button Inside List On Page Load
Jan 4, 2010
I am using two data list one at the bottom & another at the Top to display paging. On Page load, I need to access link button placed inside Data List. Actually I had got two Datalists. I can access one Datalist Link button like this:
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:
I need to change this label to a link that will cause C# code behind to:
tbxCG_ID.Text = Eval("CG_ID") and then call this: protected void ListBox1_SelectedValueChanged(object sender, EventArgs e)
I keep creating a DataList1_SelectedIndex_Changed event created when I double click the label or a link button. What is the code needed? I can see the Eval("CG_ID") value with the label but I don't know how to get it into tbxCG_ID.Text and fire the ListBox1 event.
I have a form in which user select the number of policies.say 1 or 2 or 3..
When user goes to the next page, based on the number of policy selected in the previous page, i hav to change the link button's image respectively. ie if user chose 1 the button should have 'Continue' or if the user has chosen more than 1 then button should have 'Next Policy'. I am aware that this has to be done on the page_load. Basically how to change the link button's images at runtime based on a condition.
I'm trying to get a link to load a new page that passes a value to the new page. To my dismay I've found out (or im doing it wrong) that this doesn't work in the repeater.
[Code]....
How would i get something like that to work in my repeater so it can show a new News page with more information on it.
I try to make button inside datalist to be invisble based on a column value from database. I am able to read the column data but i cant find solution to make the button invisible. Below is my code behind:-
I have an issue that I've spent quite a bit of time trying to solve. I have a Detailsview and a Gridview that I have linked using the ID field, It has now been decided that they want to have individual pages for each Unit. I have this working for the most part, however the detailsview is not being displayed until I hit select the row in the gridview.
How do I get this to automatically display on page load?
I have a grid with an link button template field i also added a drop down list template field, i would like to hide the link button text (select) and display my drop down list for only the current row, when the link button is selected and capture the selected row (int row = gvstaging.SelectedRow.RowIndex;)
When the dropdown list SelectedIndexChange event fires i would like to access the value of the selected item(
DropDownList ddl = (DropDownList) sender;string s = ddl.SelectedValue;) and pass the selectedrowIndex and value to another function
I know how to get selected row index , selected value from the ddl but dont know how to hide one and display the other only for a row and pass both values to the next step
I have a datalist and the following link button within the datalist:
[Code]....
I would like to post to a new page and then capture the value from the link button (commandArgument). It appears from other threads I've seen that you have to rebind the datalist in order for the ItemCommand event to fire...is this true? I'd hate to make another DB call to bind my datalist just to make an event fire.
VS2008 ( vb.net ) I created a test page with a gridview and link button on it. in code behind i placed the following code
[Code]....
this works perfectly .. however, if i set up the same page, but use a master page as well ... then that code doesnt work. GridView1.Rows(e.CommandArgument.ToString).Cells(15).Text.ToString() is empty
In my gridview i am returning values from database in which 'filelocation' is containing location of pages over my server and i want to use coustom linkbutton in templete field to raise a event and set session variable and then redirect to that page .
My question is how to get value fron 'filelocation' coloum in gried view when a linkbutton in clicked and onclick is fired and also set session value at taht point.
How do I conditionally trigger a full page postback from a link button inside of an update panel?
I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.
Here is the control hierarchy:
Page Custom Control UpdatePanel LinkButton
Event handler Pseudo code:
LinkButton Click Handler Begin If is a partial post back AND a full postback is needed Page.DoFullPostback End If End Handler
Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.
i have created a .net chart, but when i load the page to see the results, all i see is a blank gray rectangle. no graph inside. (while if i split view it in VS i see the chart)here is my code,
I built a simple application that is used to manage photos for an image gallery on my employer's website. A user can add, edit, or delete items which are stored in an XML file. I've set up Up/Down buttons so that I can move pictures up and down in the order.On the first page, I've disabled the Up button of the first item on the RowDataBound event... since it's already first
[Code]....
I'm trying to do the same for the Down button on the last item of the last
I have Link Button to Export to excel in Master page. Since I have placed it in master page I can see Export link button in every page. I need to disable link button where gridview is not present in a page.
I thing using Enabled property we can do. How to proceed. Is there any other way to do it.
<asp:LinkButton ID="LinkButtonExport" Text="Export to Excel" runat="server" OnClick="LinkButtonExport_Click" />
I have a dropdown control that has a list of names in it called PlayerNameDropDownList_Insert and a textBox called PlayerName.
When I select a name from the dropdown it populates the textbox correctly.However, when the page opens the first name is selected in the dropdown but nothing in the textbox. How can I get the textbox to populate with the value of the dropdown at pageload?
I have a boolean / bit value in the database called "is_paid". Depending on this value I want to Disable a button. (the same would go for example to set a textbox not Visible, but anyway)
What I want is to Disable the button, if my boolean is 1 (true).
First I tried to convert my boolean value to text:
CS0030: Cannot convert type 'string' to 'bool' However, if I use it one a Label it works fine: <asp:Label ID="lblIsPaid" runat="server" Text='<%# Convert.ToBoolean(Eval("is_paid")) ? "True" : "False" %>'></asp:Label>
So another trial I did was to CAST the data from the database to be the text that I want, like so:
SELECT not_paid = CASE WHEN is_paid = 0 THEN 'True' WHEN is_paid = 1 THEN 'False' END ....
System.InvalidCastException was unhandled by user code Message=Specified cast is not valid.

So I wonder, is it possible to change the "Enabled" property based on by boolean value?
