Forms Data Controls :: Loop Through All Gridviews On Page?
May 26, 2010
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;
}
}
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 have a web page which has about 11 gridviews.Hence the page takes bout 15 seconds to load.The grids are 1 below the other.They are populated at the page load.
I need a solution to reduce page load time. Is there a way,where the gridview loads only if user scrolls to it. I donot want the user to make selection for everytime he wishes to see a gridview. The page should show gridview if its data is bound to it, not waiting for entire page gridviews to get populated.
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 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?
the project I'm working on has become quite bigger then expected. And now I have pages containing about ten different GridViews (and it is likely to increase!!), each one with its own EditItemTemplate, ItemTemplate, FooterTemplate, style, properties, etc. And, of course, in the code-behind (C#) each Grid has its events handled. You can imagine: it is a mess, playing with visibility of each one, ImageButtons to hide them, further buttons for other actions. I decided to handle only events in the code behind, while using partial classes and additional classes for the rest of the code (SQL queries and everything else), but still, it's gettin a mess.
Well, my question is: is there a way to, how can I say, have a kind of separate files, where these objects are deployed, and from where I can reference them when running the application. Or, if it exists, a way to lighten aspx page and asp.cs pages. I know it's part of the job, so here the question is just intended to investigate whether a possibility to "distribute" the objects used in a web page exists.
I have a page for a client that currently is setup to display a gridview for each subcategory. They recently added a new subcategory and they were wondering why it wasnt showing up on the page. Well the way i have it setup, i have to create the gridview adn datasource for the new subcategory.
Is there a way to setup the page to display a gridview view for each subcategory so if they decide to add another, i dont have to update the page with a new gridview adn configure it? I would like to be able to update what i have and provide a more flexible setup for them.
keeping i mind that each gridview would contain different result sets, is this possible? if so, what controls would i use?
I have two gridviews on same page - If a record is selected in Gridview1, I need to unselect a record (if one is selected) in Gridview2 - and vice-versa.
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?
I currently have a GridView control on my aspx page with paging enabled and I need to loop through the entire row collection/count to process the selected records. With my current code, it will only loop through the current page of GridView row.
foreach (GridViewRow data in grid.Rows) { //here is my code }
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'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'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 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?
I have created a page which contains multiple gridviews for a large report. They now want to have a nice printout of these gridviews in Word.I am able to export multiple gridviews into Word fine, but the problem is I want to add a heading in between each gridview and am unable to do so.
I am trying to export multiple gridviews to Word. I am able to do this but what i want to do is add some headings and text in between each grivdiew. Please see my code below i am using to export the gridviews.
I have a form with a ton of gridview controls on it. All of which are driven by a dropdown list control. When I select a value from the dropdown list control it populates the 5 gridview controls with data from the database.If there are no rows associated with the record from the dropdown list then I am going to set the visible property of all of the gridview cotrols to false.
I know how to set the property I just need to know where I would set it and what I would check.I can put my code in the selectedindexchanged event for the dropdownlist control but how do I check to see if there are no rows associated with that value? Maybe some sort of If gridview1_rowdatabound = 0 then...
