Forms Data Controls :: Make The TextBox In The Gridview Template A Datasource?
Feb 6, 2010
I have a datagrid, with a template with a textbox in it. I am trying to add a "update" feature to my datagrid, writing my own code. Stuck on one thing though. I try to update the DataSet with this code:
[Code]....
But when running the code, an error message is showed saying that there where no changes to the GridView. This should probably be because the textbox in the gridview is never declared as a datasource for the gridview. How do i make the TextBox in the gridview template a datasource?
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 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 !

I am trying to add a Ajax AutoCompleteExtender to a Textbox (template) in a Gridview.In a different projects I have used a A.C.E with a Texbox on a form and it worksIn a different project I have used the gridview RowDatabound event to locate and added attributes that monitor keys stroke and the like (via java)BUT :(I am having a problem getting my head around how I connect the Ajax A.C.E to the Textbox in the gridview.My guess is, it is probably by adding an attribute to the textbox of the gridview but how do I reference / link the Ajax A.C.E.ORHave I just got in complete wrong?My aim is to add a combobox to a gridview ie a dropdownlist that the user can also type into.
I have Gridview that is populated from a data table, there are two additional template columns which are not bound (one checkbox and one textbox). I intend for the users to fill data in the unbound textbox and check the checkbox as needed. (there really is a good reason why the data is constructed in this way)
here is the problem, when the user enteres data into the textbox and hits enter, the gridview appears to postback, which wipes out the checkbox and the data in the textbox.
I tried setting the enable view state of the grid to false, that was supposed to stop postback but no luck. I have the enable view state of the textbox and checkbox set to true and autopostback set to false. but still no luck
so I need to either stop the postback or intercept the enter key in the text box and cancel the action, but that is a bit beyond me at this point
I have been asking this for a long time.But the answer what i get is not want i need.I have a gridview with two template text box (t1 and t2) inside gridview and four textboxes outside the gridview on the form (txt1,txt2,txt3,txt4).All these textboxes allow only integer value to be entered.What i need is to get the total of all these textboxes (ie,template textboxes as well as textboxes outside gridview) in a textbox named Total at the same time we enter values in a textbox.Also if i change the value of a textbox later that too should be reflected in the Total textbox .I know how to calculate the total of the textboxes outside the gridview.But i need the total of all textboxes including template as well as textboxes outside simultaneously
I have a webform developed in VB.NET and I am facing a strange problem. In the webform I have a GridView control which has two bound fields (Item # and Item name) coming from a master table and infront of these two fields I have placed a TEXTBOX control as TEMPLATE FIELD to take any value of particular item. But after filling all the textboxes when i clicked on submit button it loops thru the items and there i need to read the textbox value of that particular item in a variable but unfortunately the value is blank even the data is there. Here is the ASPX code.

Values for multiline textbox in gridview are coming from SQL db "text" type previously entered by user...sometimes a small amount, sometimes a lot. Want to display enough to make it readable without wasting space on the screen. Can't believe this mechanism is not built in but have researched & see I may have to count lines then set the "number of row" property.
Question 1: Should this be done in databound or rowdatabound event?
Question 2: Could someone provide the "row counting" code (in C#)?

I have a template field in datagrid. The field shows in insert mode. I do not want to show it because it is a thumbnail to an attachment. The regular bound fields have a setting "Insert Visible" which could be set to false - that is supposed to hide them in insert mode. The template field has no such thing. I have even tried to put Insert Visible = False in to the source but to no avail.
My definition of the template field looks like this:
I've been trying to find a solution to my problem for about 2 days now, and have found nothing. I am new to .net and not really sure how to accomplish this. I have 4 tables in a database, Vendors, RepairCos, Cons, ConRepairHistory. What I'm trying to do is make a page called SendOutForRepair.aspx that has a insert item template where the first control is a dropdownlist that is attached to the Cons table (got this figured out) and is populated with the Serial Number field. I would like the selection from the dropdownlist to populate the 2nd control (VendorID) that is also from the Cons table....
