i am implementing a update query module.i am displaying all fields from a table for a term searched. well now i am implementing update option for the record which are displayed, i have like 70 columns in my table, and i want to know how to restrict some selected fields to be only read only while the form can be updated ?Like if user select to update a record then some selected field such as "Timestamp, UID etc some selected fields" remains READ ONLY !
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
I've been searching in all the forums, and websites for the last 4 hours without finding a solution for a problem that in the beginning I tought it was an easy one!!!This is my problem, I have a gridview with the following colums: select (link), Room Type (for hotels), and TotalThe total field Is a template field it has in the custom binding property a function: find_total(Eval("Room")) this function makes some calculation and returns the calculated Total value, and shows in the gridview without problems,The thing I cant do is: when the user clicks on the select link I want to get the text of the template field and put in a label control.
I tried, almost all the events of the datagrid, to reference the content of my template field but sometimes I receive a null value (seems that Im looking for the value before the find_total function has been executed) or I get an error "the index is out of range".I dont know how to approach this, I tought It has to be much easier, but Im very confused right now, if anybody knows how to do this
The linbutton shows Purchase_order_no. When i clicked on a paricular purchase_order_no., it will navigate to another page with a gridview that shows details of that particular Purchase_order_no...
I have a Linkbutton on a Gridview which has got the below RowDataBound:
[Code]....
The above javascript will close the page automatiically. My intent is to close the page after the Link in the template field is clicked, but here the page closes automatically when its loaded.
I have a gridview, whose columns I am dynamically binding. There are two fixed columns, one is a button field and another is a template field containing an image. The other columns might vary in number and behaviour, so before binding the grid, I am removing all columns of the gridview except the button field and the template field. But after doing this, if i try to do a findcontrol for the template field(Image column), it is notgetting the control. Means while removing the other columns, this image control also getting removed.Below is my code:
[Code]....
Now, after this i call the databind method. The problem is with the for loop, where I am removing the columns after the image column. And I am not able to find the control after that.In rowdatabound i am trying to find the control like this:
I have a grid view with 2 text boxes as template field.....I have to do client side validation like data type checking and comparison of the textbox values.I tried many ways...Required field validater is not working .I guess may be because I am not posting back to server for individual row but single click updation at the end of editing.I am trying for 2 days now....I am not able to connect grid view templates with java script functions.

I have a gridview where I am using the update. I have converted the label into a templatefield and added a dropdownlist which is getting polulated in the Rowdatabound event. When I test the update i get an error
Cannot insert the value NULL into column 'StartTime', table 'HTC.dbo.EventDates'; column does not allow nulls. UPDATE fails.The statement has been terminated. so I am ussuming its still trying to update from the label rather than using the dropdownlist. here is my code:
I have following codebehind in ASPx - VB.Net in my aspx project, i want sum a template column (txtAmount) to show another TXSum template (without any postback) any one give me a better soluation in javascript.
I am using an IComparer to do the sorting of the gridview and binding it to a list of objects. It used to be that the linkbutton in the first template field was being done like this:
[Code]....
The sorting worked just fine when it was like this, but I would prefer not to use a querystring value. The problem with using the linkbutton is that the sorting appears to work (there are only two rows in my test case and they change places), but when the linkbutton is clicked on it is in the same order before the sort took place. After each sort the gridview's datasource is reset to the newly sorted list of objects and the databind method is called.
I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.
After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...
I have a GridView that is bound to a DataTable containing questions. Each question has a possible score of 1 to 9 which is handled by a Template Field with a RadioButtonList databound to another DataTable (containing the values 1 to 9). This all works fine except as an added complication, some of the questions have an extra choice in another field. So the problem is how do I bind the second Template Field to a datasource that is dependent on the question. It's like passing a parameter to the datasource of the second Template Field, the value of the parameter being the Key Field of the particular row. Is this possible and if so, how do I do it
now I want when users click on hyperlink according to above table if their behcode=1111 it go to show.aspx(it is anotherpage that I made) else it go to View.aspx page/
I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
I'm trying to remove a GridView Row if the user has checked a checkbox in that
[Code]....
row (the checkbox is in a template field), but I'm unable to actually remove that row from the GridView. Here's what I have, I think I'm getting the row index incorrectly...
I have an application that I would like to be able to allow the user to modify multiple characteristics of each record within a datagrid.
Most characteristics require data to be entered in a text box but some a check box would be more appropriate.
My question is does a gridview column need to have all the same item template controls? or could I read from the database the control type and dynamically alter the template control for each row as it loads?
