It seems like this would be fairly straight forward. I've got a gridview that loads up using one stored proc, but I've got a searchbox to filter the grid, and when the user enters some criteria I want to use a different proc to return the results. Something tells me I should be doing this with one procedure, but I can't seem to make that work either. When the form loads, my grid is populated. And if I leave my search criteria blank and search anyway, my grid is still populated correctly. But if I enter search creteria, I get diddley squat. What gives? Here is the relevent snippets.
There is a page in my project named Messages.aspx that shows the messages received [but obviously], using the ListView control.
I want that the user should be able to see the body of the message on the same page [Messages.aspx] just by clicking the subject of the message, which is ofcourse a link.[Messages.aspx?msg_id=some_id]. Hence the user would actually reload the same page to read the contents of the message.
Now what I want is that I should be able to write some code that would change the <LayoutTemplate> and the <ItemTemplate> of the listview during the runtime. [in the page_load event of course]
Previously the listview would look like this:
[Code]....
After the clicks any message to read it and the page gets loaded, I want the layout of the listview to look like this.
I have a DetailsView control with a SelectMethod and two select parameters wich one of the parameters is a control parameter, The parameters are not passed to objectDatasource's select method, the objectdatasource has been defined as follows:
What I have is a command column with 2 link buttons, Review and Update. The Review link will show a more in depth look at the record (pretty much a detailsview) The Update link will allow the user to edit a few select fields. The Update link works fine, because I put the code in the GridView3_SelectedIndexChanged event. When I click the Review link (which has code in the LinkButton1_Click event), there is no data from the Selected row, because the row is not yet selected. Is there a way to trigger the selection BEFORE the button click event? It seems like this should be easy, but I haven't needed to do this before.
I'm trying to allow my users to select a record from their list of attendees and edit it using a details view positioned below the GridView. The issue I'm having is when I run the code I get my error message and no data is displayed in the DetailsView. Error Message is:
DataBinding: 'System.Data.Common.DataRecordInternal' does not contain a property with the name '10002'.
I want to have a dropdownlist in the footer row of a gridview. The dropdownlist must be populated with an stored procedure that receives a parameter and has a select. Is that posible?? I think yes but I having problems with the parameters.
[Code]....
The exception says incorrect sintax... but I've changed the procedure for something very simple to solve the problem like select 'hello' or select 1, 'hello' and I'm getting the same problem...
I have an accessdatasource with multiple columns, one column I use it to populate a dropdownlist. Can I use the data from other columns to insert into a table, insert being done in the aspx.vb page, without creating gridview etc.
Is it possible to make a detailsview one column visible= false and still be able to evaluate its contents?
The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
I looked on some tuitorials also but i still have few confusions.
I have a few parameters on page A. After the selection of those parameters, i should pass to the new page which should have a list of fleet items. There will be few columns and at the right most, i want a tickbox whether to select that item or not.
As a default, i want each checkbox be checked but if user wants to uncheck it, they should be able to do it.
I'm having problems binding controls at runtime. I've some user controls which need to be bind to the page when one of the dropdownlist selected index changed.
I can able to bind them properly but when if there is any postback event happens I am losing the controls and control values which were created runtime.
When I want to get the output values its okay but I also want returning a table as a result data.But Datareader has no rows.is it possible if I want a returning query result and multiple output values togather ?I wrote a test above.I can get output values as sqlparameters. But Datareader attached to a Gridview is empty.can you detect whats wrong here and it doesnt return a query result.So stored procedure is not standart or ı am doing something wrong.this doesnt raise any exception.but not returning any data.
I'm basically trying to get a div containing a loading gif to show on my page at runtime. I call it from a button click event as well as in the code flow. It was working before I used the AJAX Update Panels. I've since taken them out as they were causing issues with RegisterClientScriptBlock. By the way, does commenting out the AJAX Markup like this...
I have a site map on my project and I have section which get values from sql database and it changes according to querystring Id value. In my sitemap the title of the page is everytime same. but I want tpo change it at runtime. I am using multiple sitemaps and My sitemap is not the default one. its name is rootSitemap. I tried some code which I got from msdn but it seems doesn't work for me;
[Code]....
Here is my sitemappath code which is situated in my master page;
hw can i give write permission to folder for changing the image at runtime.i have tried so many times but still confused and free hand. can some one pls give me the solution in details.
I've an item template inside a grid which has a <asp:LinkButton/> inside it. I assign the text for the link button as
<%# Convert.ToString(Eval("Tags"))%>
Tags can have a string with multiple tags in it delimited by space. For eg. "sports", "sports cricket", "sports cricket sachin" are the examples of some possible tags.
I want to create a button for each tag inside the string. How can i create the controls (server control - linkbutton) dynamically during runtime inside the grid item template?
I have a requirement whereby one or more image buttons need to be created in a user control at runtime. The number of buttons is determined from a database where a user can add one or more rows that contain an image for each button, so if a user adds 3 images to a table, 3 image buttons are created. Ive used this code but I get an error at runtime
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.
[Code]....
this is the usercontrol aspx
[Code]....
I basically want one or more buttons to render within the div in the usercontrol. Ive only got the code written for one button at the moment while I test the rendering, eventually they will be rendered in a loop of records taken from a database. Whats the best way to do this ?
I need to create aspx pages on the fly or at the runtime.I read that creating a template page and posting content to the page would be a solution, in a few posts in the forum. Can i get information on this method.
