Data Controls :: Updating GridView With Readonly DateTime Value In TemplateField
Dec 21, 2013
I am trying to update values in the GridView but have some issue with the Datetime (which I want to keep Readonly). On updating the GridView, I am getting the following error:
ERROR: "System.FormatException: Input string was not in a correct format."
I want to convert datetime format as per local date time format from GMT formatted date timebinded in a gridview using Boundfield using javascript only.
I have a SQL2012 database in the database in have a table with many cloumns one of the columns is date. on the gridview i am using a ItemTemplate field to display date
The Problem i having is that i am testing weather the date matches something and based on that it display "" else it should display the date based on the formotting but both are not working.
I have one two GridViews on a page. One Gridview uses BoundFields inside of the GridView and the Update statement works just fine. The other GridView utilizes TemplateFields due to the fact that Validation Expressions have to be used. I also want This GridView to be able to update the vlues when the user clicks on the Update link on the right side of the GridView. The GridView that uses the BoundFields updates just fine, but the GridView that uses TemplateFields will not update. I have checked and everything is correct other than this difference of BoundField and TemplateField.
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:
Im using a LINQDataSource to populate a GridView of Universities.
Each University has an associated State, which is in another table and associated by a foreign key (StateID).
I have a TemplateField in the GridView so that when you view it normally it displays the StateName which comes from the State table and when you edit it shows a DDL populated with everything from the State table.
[Code]....
If I debug, inside of RowUpdating, GridViewUpdateEventArgs.NewValues doesnt even have a key for State.
Question: How do I let my gridview know I want it to update this column? All the BoundFields just seem to work...
I need to change ReadOnly from false to true for one column in GridView depending on who the user is. In my particular case it is a BoundField (also I would like to know how to do it for a Template field as well) and DataField is "dteRequired". I would like to code something like that right in the Page_Load handler:
I have a problem specific to the gridview control, i am using the datasource to generate an update method for the data in my table.
Some of my columns are display only fields so i have set them to "read only = true" Everything seems fine when the page loads but when i click update, the columns that were editable update fine but the ones set to read only have now updated the databasewith a null value. Am i missing something here?
I have some custom Code to handle the Insert And Edit Mode on the OnRowCommand="CheckTheData" property of the GridViewThe Grid Starts in the "Readonly" mode, click on the edit button and it goed into edit mode for that row My routine ends with:The update is done and the display refreshes, but in the edit mode. If I click the clancel button back to read only mode.How can I get the gridview to redisplay in the read Only mode after the update?
I want to create simple rating page where player's place,name and rating is displayed. I've created database with ID,Name and Rating Columns, binded Gridview to this database and created TemplateField "Place". With following code I've created numbered list for Place:
protected void Page_Load(object sender, EventArgs e){ for (int i = 0; i < GridView1.Rows.Count; i++)
I have a GridView, bound to a table (Meals) in a SqlDataSource.
Into that GridView, I have added a TemplateField, which contains a DropDownList (which displays the numbers 1 - 10, added manually; no Data Binding). And, I've added a ButtonField.
When I click the Button, I want the values of some of the GridView rows PLUS whatever value was selected in the DropDownList to be pulled out and stored in a second Sql table (Orders).
Pulling the rows bound to the SqlDataSource is easy but JavaScript is needed (I think) to pull the SelectedValue from the DropDownList. I understand women more than understand JavaScript (that's how little I know) and the code below has been kindly offered by another forum user who is at a loss, himself, now.
Here's the code and the error message I'm getting.

And here's the Code Behind:

No design time errors reported but here's the run time error:
Object reference not set to an instance of an object.
On the following line:

I'm relatively new to the VS environment. I'm using VS2010 Beta 2 with VB. I have a Gridview setup to pull a list of employees. Next to their name I have edit and delete icons. When I leave the icons as ButtonFields, they pass the DataKey value to my code behind perfectly. When I convert the ButtonFields to TemplateFields, they no longer pass the DataKey.
I have problem while set or passing value from code behind to asp:label inside gridView asp:templateField. 1st. I have gridView and using SqlDataSource control for data source. This is my gridView code?

2nd. I have SqlDataSource for my GridView. this is the code :
[Code]....
We can set value in the *.aspx or design view by using <%# bind("str_isi") %> like the asp:label control with ID=lblGvPengumuman but how we can set value in code behind?
i want to sort a gridview column which is a template field with a repeater control in it. this column has multiple links and i would like to sort using the first link. how can i achieve this.
Though it is usually not a big deal to edit the source code to accomplish this, I am just curious if there is an easier way to reverse the conversion of a column to a TemplateField. The covnersion can be done by a simple click. Is there a similar click to reverse it?
