Data Controls :: How To Make Bound Field And Template Field Read-Only In Edit Item Template Of GridView
Jul 31, 2013
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 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.
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 have a gridview which the columns are created programmatically.
When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
How can I add a item template in the template field I created which is binded in my datasource. Also what event handler should I use to do this.
Here's the part of my code:
Someone know how can I bind a label item template from the datasource. The label item template should be firstname + middlename + lastname.
If im not doing it programatically, it will be just concatenating eval(). But how can create item template and bind it programmatically?
in my website there is a module in which i m fetching the data of present students in the gridview and i m entering there marks in the gridview textbox column (created by using item template)...I want to add required field validation to the textbox columns so that after clicking the submit button there should be an error message displayed if any of the textbox is empty...
i have a gridview which consists of databounds and dropdownlist control. When I press the Add Grid Row Button, it will insert a row. Now my question is, if the user selected an item in dropdownList in the firstrow and the user click the AddGridRowBtn Again which will generate the 2nd row, how would i maintain the selectedItem in the dropdownlist after postback?
I have a gridview ...asp 2.0 and VS 2005.The Gridview has template fields and I am using a Header Templete and an Item Template field.Within the Item template fields I am using a asp: table and within the table I am using different asp controls to bind data to the gridview
Here is the issue ...I want that each datafield should align with each other eactly i.e. symmetricaly each column wise.The problem as of now is that as each row of data is displayed in a new table and as a result each column aligns differently.How can I align the columns with each other?
I have seen several Web Sites that use GridViews that have lookup fields with different Value and Text Fields (as in drop down lists) but I can't seem to figure it out how to display the Text Field in the Item Template when the Text Field is not in the datasource. .
Here's what I have. I have a Gridview whose datasource is a Linq to SQL Invoice table, e.g.
InvoiceID CustomerID InvoiceNumber
THe Customer table is related to the Invoice Table thru the CustomerID. The relationship is defined in SQL Server and is displayed in the DBML.
I have created a template field for the CustomerID field in the Gridview. I would like to display the CustomerName when the Item Template is displayed and a DropDownList in the Edit Template. The DropDownList works great, but I cannot seem to figure out how to display the CustomerName in then Item Template.
I seem to remember seeing in some video that you can simply drag the CustomerName into the CustomerID Item Template Field. But I can't seem to find the customerName field. The DataSource includes the Customer Table because of the relationship, but no fields are displayed.
I suspect this is real simple, but I cannot seem to find an article or video that explains how to do this.
I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.
I'm using a formatting expression with a template field. When the details view goes into edit mode the formatting is applied. It looks great because it applies the currency formatting. It shows up as "$60,000.00" instead of "60,000.0000". But then when I do the update it gets rejected because of the $. Is there a way to keep the formatting for the user to see in edit mode but remove the $ when doing the update so I don't get the error?
The error: Exception Details: System.FormatException: Input string was not in a correct format.
I have a doubt regarding displaying data in gridview. I have comma separated values in a particular field in my database. Will I be able to display the comma separated values from db table in a control in the Item template field of my gridview?
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:
have situation here. On checking checked checkbox inside template field on grid view. This my codethis code suppose to be update into mysql when checkbox of each row being checked. Mean only update database which row has being checked, other wise the data inside database not being updated.What happen now once button being click, code above will be executed, but all the data being update not considering the checked checkbox only.
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:
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.
