I have a blank/unbound GridView control on my form and I am binding it in the code behind like this:
GridView1.DataSource = _dataSet DataBind()
Running this code populates my GridView control with all the columns and data that _dataSet has. I want to display only some of the columns, change the column names, and rearrange some of these columns too (i want the last column from the actual sql database table to be displayed first in my GridView).
The object 'lst' is filled correctly with data. I have List<string> items in AName and DurationTime.I don't have an error, but I don't have any results.
I am not sure if I'm in the right forum but I try anyway.I am making a webproject where I have a database with tables Product, ProductDetails.In my pageLoad event I am retrieving the information from these tabels in two lists: productList and productDetailsList.
Now what I would like to do is to databind these lists in code behind to my ListView. I know how to do this if I only have one list but in my case i have two and in my listView i have fields whose information is in productList list and others in the productDetails list.
Is there a way to achieve this?
Here is some code where I am databinding one List to ListView:
I'm trying to add html text to some repeater items during DataBind, but the html text isn't parsed into controls it just displays as text. If I copy the text and just add it to the asp.net page it works fine so I know my syntax is fine. So is there a way to dynamically add more html text during the data-bind phase?
I have a paged ASP.NET ListView. The data shown is filtered, which can be controlled by a form. When the filter form changes, I create a new query, and perform a DataBind.
The problem however, when I go to the next page, and set a filter, the ListView shows "No data was returned". That is not weird, because after the filter is applied, there is only one page of data.
So what I want to do is reset the pager. Is that a correct solution to the problem? And how do I do that?
I want to add StyleSheets programmatically in the head section but one of the examples I saw seemed to need to many lines of code to add just one style sheet even though I may need a lot: Example Code:
I also use Page.Header.RenderControl() method but it didn't work either. Object null something error was thrown. I also used Page.Header.InnerHtml and InnerText += "<link .... "/> things but they threw the Literal error which is I think common error. I used this code :
It worked at first but when I change the pages it stopped working. I am using Master Page and I am writing these codes on Master.cs file and also some people recommended to use this.Header instead of Page.Header but when I built it throws an error which says I cannot declare that like this. It shouldn't be that hard to add many styles.
i'm opening a new window and passing on to it variables in a querystring, the values are loaded into a function that is filling my dataset and then filling my Gridview. after i press the button field in my grid to delete an item, the databind doesn't show the updated grid but remains the same. i've noticed that if i navigate back and refresh i see it correctly. in FF btw no problem.
I know how you can set an tag's url attribute programmatically in c#, but it seems when I try to access the image element inside of a tag I cannot access it. The is residing in the <AlternatingItemTemplate>. NOTE: I am only having this issue inside the <AlternatingItemTemplate> Now the ListView tag is also databound.(this is probably why I cannot access, because it isn't guaranteed that it will even exist perhaps). How can I get around this so that I can display my images programmatically or is there a better solution?
I'm dynamically creating image buttons and want their click event to update an image in the update panel where only the panel updates- not the whole page.
I have created the image buttons click event and got it so that it updates the image in the update panel, but I can't seem to create the triggers- I keep getting the error 'Multiple Controls with the same ID' and I can't understand why.
I have a user control that needs to load a child control when a button is clicked. The trouble is that it has to request the control from another class.
So in the button click event, I call the function to get me my control, and add it to the page, like this:
I am developing a custom Web Interface Browser for Subversion Repositories with C#/ASP.NET and SVNKit (Converted to .NET assemblies using IKVM.NET). Is there any clean way to locally add a new subversion user (that is added by the administrator) using C# code?
I have a problem with adding programatically FilteredTextBoxExtender (i put the code below).
The problem is that nothing is outputed when page is renedered although TextBox and FilteredTextBoxExtender are added to container (table cell controls property in my case).
What's occurring is that I'm explicitly firing an event so that the parent web page can monitor this and take appropriate actions. Thus when the user clicks on a different ListViewItem it triggers the population of associated data elsewhere on the web page.
This all works fine except for one thing: When I first load the control I'm pre-setting the first ListViewItem. Unfortunately, just setting the ListView's SelectedIndex = 0 doesn't fire the aforementioned event handler.
So I started investigating how to call "listView1_ItemCommand" but couldn't figure out how to instantiate the "e" parameter.
Can anybody tell me how I can add ItemTemplate to a Template column in a GridView. What I am doing right now is that I am adding Columns to GridView from code. And now I need to add a Template column with a ItemTemplate.
I have a page called Page2.aspx and it is called by another page called Page1.aspx and Page1.aspx passes two parameters namely: Name and Category to Page2.aspx. Does anyone know why the following code from Page2.aspx is not working and it keeps giving an error message as follows: " You have declare the parameter @Username".
