Forms Data Controls :: Displaying A Datatable In Gridview, Having Trouble Lining Up The Rows
May 22, 2010
So I've been teaching myself ASP.NET and VB for about 3 weeks now, having trouble with datatables, not sure how to get the rows to line up like I think they should. My code:
[Code]....
Which gives me the data output I want, but the days are adding rows underneath the previous day instead of lining up side-by-side. The idea is that once it's working I'll replace the specific dates with calendar controls. The gridview currently outputs like this:

I am working with GridView/TelerikGrid control. It is having filter option. When I filter the data,
I need to copy only filtered rows into Datatable for further processing.
Suppose I am having total 10,000 records. and when I filter on column say Dept="IT", I get 1000 records in grid. So these 1000 records only should get copied into Datatable. So How to achieve this ?
Cwhat can be done over this ? I tried number of properties for grid. But there is no property which will return fileterd data source. Also I am not able to go every page of Datagrid and collect the data. I can get data for first page only. If I need to collect the data by going to every page of gridview, what is the way for this ?

In my continuing effort to build a search page that sends gridview rows with a textbox txtQty <> 0 to a listbox via a datatable, I've written the following:
[Code]....
The page runs, I'm able to input values into the textbox and when I press the Add to Quote button inside my gridview, nothing is populated inside my listbox. Am I correctly binding my datatable to my listobx?

I see from google that this is a common problem. I have a SQL server database that contains 26 rows of data. Two columns, the first is PK and an identity column (keys numbered 1 to 26) and the second column is a text field (nchar(10)) containing a letter of the alphabet (A..Z). The letters were inserted randomly to simulate sql being unsorted by default. I have a query that returns all of the data ordered by the letter column ascending. If I execute the query in sql server I get 26 rows orderd A..Z.
I have a gridview that is set up for paging (page size = 15) and sorting. When sorting is disabled, all data is correctly displayed on the gridview, 15 rows on the first page, 11 rows on the second page.
If I enable sorting, I get 15 rows on the first page and 11 rows on the second page, however on closer examination I find two letters missing and two letters duplicated on both pages. If I navigate to page two, then back to page 1 I find that the data is then shown correctly and the missing letters are back.
Has anyone struck this issue? I am thinking that the sort is not being initialized correctly, but am not sure where to look.

I have 2 gridview controls gathering data from 2 different tables and I want them to line up on the screen so they look like one big table.
Each table has the same number of columns but the 1st columns on each grid view don't line up. Both are set to 200px, all other columns are 40px. The data in one has say 5 letters in the 1st one and 25 letters in the second one.
Is there a setting I need to use to make each column 200px?

I have a gridview and the gridview contains some boundfield, templatefield, checkbox and an update command button.
When I click the update button, I want to update only 2 columns. So I made rest of columns readonly=true.
BUT, there is a template field and I am changing the value of the template field from code behind. like below
[Code]....
I do not want to update the above column. so when I click update button, the rows having value more than 0 is working fine.
BUT The rows displaying "Expired" (value less than 0) showing error. It says "Object reference not set to an instance of an object."

I have a following scenario - A use selects criterias from a webform (C#) - a result is then returned from the sql. Say, to start, there are 2000 data returned from the sql and are stored in a dataset.
Now, the user wants to choose a number of drops (up to 6) - with the number of drops selected, they can enter their own quantity in each box. So, they can divide the 2000 records into 6 different drops. With each drop, there is campaigncode created based on the mail date and the job number they provide.
So, now i have the 2000 records in a dataset. What i want to do is loop through the gridview where the user fill out the quantity depending on the number of drops (for ex: if they say 3 drops, then there will be 3 rows in gridview with 3 quantity box to fill).
In the loop, I am getting the quantity, dropdate and the job number. The Campaigncode is created as well. Then, i am looping through the datarow in the dataset; updating the Campaign Code column with the CampaignCode for the number of records thats set in a loop. It works but the Campaign Code is not populated for the next set of records.
Here is the code:
[Code]....
I think its this line right here thats causing the problem. But i don't know how to tweak this so as to accomplish what i want to do.
if (Convert.IsDBNull(DSAEFile.Tables[0].Rows[i]["Campaign Code"]))

I am trying to delete row(s) from the DataTable conditionally but I cant.
Actually I have DataList with CheckBox (default value checked=false). I am bindind DataList at run time using DataView (Dataview is created fromDataTable).
I also have <asp:Button ID="btnDelete" ....> which I am using to delete checked items in the DataList (But this functionality is not working).
The user first "checked" items in the DataList and click the the button "btnDelete". Here nothing is being deleted (?) and the DataList appears with all the items"unchecked" (even those which the the "checked" by the user). protected void btnDelete_Click(object sender, EventArgs e) . In this function I am checking state of the checkbox before deleting the row in the DataTable.
On PostBack generated by the "btnDelete", DataList appears with checkboxes unchecked therefore nothing is being deleted
Here is the DataList
[Code]....
Following is the .cs file

I have 2 series in the same chartarea. Both contain values by year (x axis). The problem is if one series does not have data for a given year, the chart will display the first value in a series on the first tick mark whether it matches the xaxis label or not.
Example:
[Code]....
Notice the 2009 value for series1 appears in the first column and the Xaxis now has 2 2009 tick marks. How do I get the values to appear on the correct X axis marks?

I have a gridview with empty data template. In this empty data template i have a table(HTML) with 4 columns. When user enters data i want to save this in a datatable temporarily at a button click event.. Again if user wants to add one more rows data that also should be added to the same table where i added previous row data. So now the datatable has 2 rows. Like this he may add any no of rows. What i want is all the rows should be displayed when i bind datatable to gridview..At the click event i am adding 1 row at a time to the datatable

I have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).
What is the best and fast way to do it?
I don't know if it is better to create a new DataTable to have the Y and after that bind them to a ViewList or something else?
I'm also looking for example in code how to select/delete rows from DataTable.

I have a ListView with Checkbox. My requirement is - When I click on any checkbox then it should return all the columns values of that row on behalf of that CheckBox. After much study I came to know that using DataTable and DataRow I can get all data of particular ID of a Row. But I am unable to work with this. My code is something like below:
DataTable dt=new DataTable();
dt=objBAL.Get_ShoppingCartData();
ListView1.DataSource=dt.Tables[0];
