Forms Data Controls :: How To Create And Fill Some Gridviews At Runtime
Feb 12, 2011
I have a SQL query that returns about 5-10 records. For each one of these records I want to query another table using values in that row as parameters and create/populate a GridView. Can I create these GridViews and SQL connections programmatically in a for loop? I mean, I can't just plop ten GridViews and SQLConnections on my page at design time because I'm not certain how many rows will be returned in the first query. What should I do?
OK I'm a total noob so bear waith me. I'm using the pubs database. I want to add several gridviews to my page in the inside of a for loop. Here is my code so far:
[Code]....
In the foreach loop, it is iterating through the publisher's tables rows, and I wamt it to query the titles table to find all books that have that publisher id and create a gridview out of it. In the code above I am not getting it right. I need multiple GridViews, one for each iteration of the foreach loop. How do I do this?
I build a DetailsView and assigned datasourceID= SqlDataSource1
I bulid select command at runtime.
string selectcmd = "SELECT * FROM CDInfo WHERE CDID=@id"; SqlDataSource1.SelectParameters.Add("@id", Request.QueryString["id"]); SqlDataSource1.SelectCommand = selectcmd; //The only problem is that I try to call the select method //but the compiler tell me I have to add a DataSourceSelectArguments SqlDataSource1.Select(); //I don't know what argument to add, so I put DataSourceSelectArguments.Empty // But it says variable "@id" must be decleared //I don't Know what's going on.
I have a a page where i am geting data in Dataset, Which I need to fill the data in text boxes.. For that i have created a property class. How can we connect to dataset to class.
I'm trying to create multiple gridviews for a number of individuals based on a selection from a dropdownlist. The user will select his choice from the dropdownlist and from there a query is run to find the number of gridviews to create. Each gridview will also have its own data to bind. I believe I have most of it, I just can't get the gridview to show up. My thinking is to create the labels, then insert a gridview, bind it, and then repeat the process all over.
How can I access the datalist at run time to create, a table layout but with the first cell having a rowspan of 2? Below is the HTML source code to demonstrate.
I want to create a mailto anchor tag at runtime. Is this possible? I've tried this:
[Code]....
Neither of these worked. I tried adding the "mailto:" in front of the {0}, but this just became part of the perceived URL. I read a post online about using data attributes to add the value as a property of a class, but I can't do that, as I'm stuck using .NET 3.5 for this project. I honestly didn't think this was going to be such a big deal. I just want to populate the email address of the anchor tag with a variable value.
I've figured out how to create the controls in the format I want, but now I am confused as to how create more than one set of them. I set everything to new and increment the names of each control, but it's only updating the one set. Here is my code:
How can I convert the following aspx code into code behind code?
[Code]....
I want the following code to be craeated on the fly (runtime). I will only add the root level grid to aspx and then in page load I want to add subsequent grids.I know we will use GridViewTemplate to add the grid but not sure how to structure it. The steps that I follow:
1. set the required properties of gridLevel01.
2. add BoundFields for level01.
3. Add template field for level02 grid....but not sure how to set other required properties like color and stuff....also not sure what position to add the subsequent gridviews.
Do I need to add the child grids to root?? I know the level2 grid will be added to level1 but what about level 3?
I have this "how to" type of question. I have a page where there are four gridviews. Now these four grids pull data from four different tables. The 1st grid retrieves data from table 1 with a where clause in it's query that comes from a hidden fileld value in the page. Till this things are fine. However, the 2nd grid has a dependency on the 1st grid and the where clause in it's query should be the data selected in grid view1. The 3rd depends on the 2nd one..and so on.
I have a couple grid views one for Team Goals and one for Indicators for the Goals I want to be able to click on an indicator and it highlight the Goal in the other grid view both on the same page. I also want to be able to click one of the indicators and open a entry screen I assume for that I use the select portion of the control?
how to move items between two gridviews. my requirement is as such that the items can be moved around and once the user clicks on the save button then only will the final items in the gridviews get committed to the database.
I do have a page that is literally overloaded with about 10 GridViews and there is a datasource for each particular one. Now, each GridView is hide inside a panel, so I only display one at a time depending on what is it that the user request. My concern is the followng: Even though I am only displaying one GridView at a time, do the others datasource are still working behind the scene on the blind side and therefore are putting a load on the server and on its performance. Or I do not have to worry about this because as long as the Panel.Visibility = False, nothing inside that panel is working.
I'm developing a bilingual web site, and therefore, I'm changing the text of the headings and the select buttons of my gridviews. I just discovered that if I set some code like below in the rowdatabound event of the gridview, the "linkbuttonish" headings get replaced by unclickable text. In another thread, I was told to change
If Session("lang") = "en" Then If e.Row.RowType = DataControlRowType.Header Then e.Row.Cells("name").Text = "Given name"[cod]...
in the myGV_DataBound sub.This works well, but not everywhere. A few gridviews are populated from codebehind, and this is where things go wrong. What happens is that - nothing happens (it's still the original heading). I added a Watch, but once the HeaderText property changed, the Watch never yielded another result, but stayed with the new value.
Now I suspect that even though the HeaderText property has changed, this doesn't get reflected in the GV when populated from codebehind.
I guess that I should write something else than "e.Row.Cells("name").Text" to still have the click-behaviour, but I don't know what.
The same question arises for the select linkbutton in a cell of the gridview's datarows.
I have a project I am doing where clients post the sale of tickets. They are stored in a DB and shown in a gridview when they login to their account. However, I need to figure out how to set the gridview to only show what they have posted. I know I can use the their login clientID(CID), but I can't figure out how to get the gridview to show post for the client that logs in. It will either show all the post by multiple clients or it won't show any at all. I am using response.redirect(clientlisting.aspx? & "CID"). I then set the where clause as ticketID(TID) = querystring to (CID) but it is not showing anything.How do I set the gridview to show only post by each individual client?
I am needing to display two gridviews in the same panel on a form. Each of the gridviews has their own sqldatasource. Both datasources pull from the same table but they have a different record selection. When I view this in the browser I only see one gridview displayed. Can someone tell me how to do this or is there a better way to get a two gridview look without using the gridview?
I am trying to loop through all gridviews on a page to hide them and set their page index to 0. This should be very easy to do and it seems like the code below should work but it doesn't?? How can I accomplsh this with the least amount of code? FYI- this code is executed on a button click.
foreach (Control childControl in Page.Controls) { if (childControl is GridView) { ((GridView)childControl).Visible = false; ((GridView)childControl).PageIndex = 0; } }
I'm creating a new solution to print a grid of my system. I think that is the best solotion, but....I need to copy some TemplateFields between two gridviews, but on the DataBind of the new grid, trows the error "the databind method like eval() only called on context control templatefield". I have Eval() instructions and I can't remove it!.Follows the exactly code:
I'm having two grid view and one button on aspx page , on click of export to excel button i want to transfer these grid view data to excel sheet.. My requirement is to trasnfer to same excel file with two sheets(One sheet for one grid view).
I have my gridviews, buttons and labels put into tables:
[URL]
Here is how the page looks when I run it:
[URL]
Then when I select an Order this happens:
[URL]
Why is it when I select an Order and the second gridview pops up theat it moves my text and Ship button down? I thought I had it setup in the tables so this wouldnt happen?
