Data Controls :: Unable To Find Columns And Change Its Style For GridView With AutoGenerateColumns True
Feb 10, 2014
I am trying to add dynamically gridview (headerstylewidth, back-color, height, etc…, itemstyle width, back-color, height, etc…), in codebehind but I am receiving this error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I want to freeze my Header columns when Autogeneratecolumns=True.
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data;
I have uploaded a excelsheet to datatable and that datatable is bound to gridview.there is a save button present,i want to click the save button and all the gridview data will save in database.but that gridview has no boundfield or templatefield.
I have a gridview with Edit and delete lini on it. I want to change the text of "delete".
I don't want to use link button because I have already implemented the code and its working fine. I just want to rename the "delete" text on grid view.
I try to add a header checkbox to selecte all in the column, I know that with templeate field you can but the problem is that i don't know the number of columns. How i add a checkbox to the header in every column?
I have a gridview that I need to get the width of columns for after the gridview is databound. I have to have AutoGenerateColumns=true because the columns for the datatable that the gridview is bound to is not going to be fixed. The problem I'm having is the gridview columns collection is not populated when AutoGenerateColumns is true. Is there anyway I can get the width of each column after the gridview is databound? I've tried using RowDataBound and going through the tablecells but the width is 0 for every column.
I have a gridview that is bound to a SqlDataSource. I programmatically change the selectcommand of the datasource, and then allow the gridview to autogenerate the columns, headings, etc. I want to set the DataFormatString for one of the columns to "{0:d}" (shortdate) before the gridview is displayed. This would be no problem if the datasource was fixed, as I could edit the column with the wizard and set the DataFormatString of the bound column. How can I do this programmatically with my dynamic gridview?
I have a column, description, in a GridView which has the most text data. As that column is defined as varchar(256), it can allow a string with 256 characters in it. In displaying, I don't want that column to stretch all the way. I use ItemStyle-Width to contain it to be 40% width. I also use word-break and word-wrap as:
I guess this attribute apply to the whole GridView1. I have a column called category with possible data as "LINKAGE", "CURTAIN", etc. Now "LINKAGE" is broken up into "LINKAG" and "E" with the "E" goes to next line. The word "CURTAIN" have the "IN" goes to the next line.
Now how can I apply the word-break and word-wrap to only the description column?
I am unable to find any control in row editing event of gridview that i have put in edit template. I have to populate the dropdown control so that in editing the user can select value from the control.
How ever i can access the controls in row updating .But i need it in row editing event.
I have a gridview that loads with a new datasource on button click event. On the gridview (which is located in a table columm incidentally) are 2 columns, a descriptor and a checkbox. The problem is that after postback, the column widths change, the checkbox column expands and the other column contracts. Is there a way to keep the gridview column sizes the same after postback?
I want to change row items colour if last column value of each row >72 therefore I used following code:
[Code]....
The above code is working fine but when I am trying to control row items to the generlized method by the following code, it is working fine but the procedure is not applying successfully for one row which is also meeting criteria:
I'm having a problem sorting a dropdown that I've bound to a SQL Server data source. I've narrowed the problem down to the fact that I have a static item at the top of the dropdown with the data-bound items appended afterwards. If I remove the static item (<asp:ListItem Value="-1" Text="All" />) the ORDER BY part of the select clause works fine. How can I get around this issue? What I would like is to have the "All" static item at the top of the list with the data-bound items sorted alphabetically afterwards. I'm using Visual Studio 2010 and ASP.NET 4 if it makes any difference.
My GridView is not updating when AutoGenerateColumns="false" and have TemplateField. It works fine when I comment out the BoundField and TemplateField and change the AutoGenerateColumns to true. Am I missing something?? Below is the markup:
I'm using a DataPager for a ListView, it works well, I'm using ButtonType:Image to style it but I want to change the image while mouse over, but I can't, I've tried some with ButtonCssClass but there's no good result. Here is my DataPager:
[Code]....
So, is it possible to change the image while mouse over?
